Good morning, I just purchased an 05 S40 and was wondering (After I searched the forum) if anyone has any ideas for a new muffler that would be somewhat louder but not just a straight pipe?  I don't want to be deaf, just have a sweeter exhaust note.

Thanks for any help!

For a beter sound,some increase in performance, less weight & a mu8ch nicer looking muffler, Id go with a Dyna H/D takeoff. Cheap & easy to get, generally. If youll be wanting to get more power than that little bump, the Supertrapp is tunable, but pretty spendy. If you go w/ the TRapp, you can swap the cam out when its cam chain time & retune the Trapp to get the most out of that. Jetting the carb & tweaking it or just swapping the carb will be a step up in performance. The Backfire issue will tell you what changes you have to make.

Is the H/D Dyna muffler very loud?  
I have been reading about the backfire issues and am going to make the carb mod pretty soon.  Right now extra power isn't important.  I am VERY new to motorcycles and this is plent powerful enough for me right now.

Thank you for your advice!

The Harley Sportster muffler is only a little louder, pleasant deep tone, and 10 lbs lighter...
For easy install find one that has a rail type mount like this one...

The Dyna isnt obnoxious. Its a stock H/D muffler. As`far as Im concerned, its the best looking muffler Ive seen on the Savage. I have a Supertrapp, not as pretty, but tunable.

No, I did it shortly after I got this bike last July. Not only could I believe all that exhaust had to go out that little 3/4" hole, it was too quiet too. I don't like a noisy bike either, so I started w/ 3/16, and enlarged them to 7/32,....just right.

Maybe, but installing one sure isn't straight forward ! I have never heard so many different conflicting stories about installing one,....all the way from,........
slipping it right on..no problem....
to ruining/buchering up a perfectly good header pipe only to have exhaust leaks afterwards, if not burning up the brake cable !

Now com on guys ...either the dam thing needs to be angled to line up, or it don't ! And either the pipe OD's & ID's are right, or they aren't.
Does it seem like the pipes are not all the same,...and neither are the Dynas ? I'd much sooner buy something that was designed to fit.
But I am perfectly happy w/ my drilled OEM ;D

Here's what it looks like.  Now, I'm not much of a mechanical guy so maybe I'm making it harder than it needs to be, but this sure doesn't look like you can just stick a clamp on and be done.  If I did something like that at my job, they'd fire me.  ;)

And if the adapter has to be made, ain't that moving the muffler back,....causing other mounting problems ?

I ain't ready for that. I'm kinda finiky too, if I have to "jury rig it, (am I allowed to say that ?) I ain't doin it ! >:(

Post by babyhog on 03/15/10 at 08:21:55

I think the difference is in the changes that H/D made over the years.  So depending on what year Dyna it came off of, depends on how it fits on a Savage/S40.

Post by Gort on 03/15/10 at 08:28:21

I bought a Dyna for my '96 and it required no alterations, welding or adapters.  It bolted directly onto my Savage bracket.  The Savage heat shield bolted directly over the Dyna.  Nothing is out of line or crooked.  I used cut up aluminum can to use as shim stock and wrapped it around the header pipe where it fits into the mouth of the Dyna.  The shoulder on the header pipe does not butt up against the mouth of the Dyna.  There is a gap of 5/16" between the mouth and the shoulder.  I used the Harley clamp that came with the Dyna.

The problem with the Dyna is that it appears to come in more than one configuration.  The Harley numbers on the side of mine are:
64941-01.

This Dyna has been on my bike for 2 years, and I've had no problems with leakage or it coming loose.  It took about 30 minutes for me to install it, and it was an easy install.  The difference between the way the Dyna in the picture posted by Siriusjoe fits, and mine, is that the shoulder in mine is only 5/16" from the mouth of the Dyna sleeve, and the Savage pipe fits straight into the Dyna, not crooked.

I've done four Dyna/Sporty installs and one Supertrap...

Rail mount Dyna/Sporty is as easy as a Supertrap... if you get a tab mount, it takes a little drillin' and tweakin'...

I do cut extra slots in the end of the muffler to allow the clamp to compress further, and use  a strip of tin can as a shim spacer,... use a good, fat clamp...
There is a very slight out-kick at the muffler/pipe joint, but the extra cuts allow the clamp to make a good seal...

If the brake cable touches the muffler, you can lightly tap the cable guide with a rubber mallet to get clearance.... or just let it touch,...

Yes, to both of your questions.  Here are 2 pics so you can see how the installed Dyna slightly angles back in towards the frame, at the rear of the bike:

Thanks for the photos Gort.  The only way I can get this thing on is to force the end of the header way over to the right.  I have to put so much pressure on it that I'm afraid of breaking the studs out of the cylinder head.   When I do this, the muffler goes on and it looks like this.  Does this look about right to you?  Should I be worried about putting so much stress on the header pipe?

For those of you who have not done this mod but are following the saga nonetheless, here is a picture that clearly illustrates the problem. Note the red lines I've drawn on the photo.  The header pipe and the rear bracket aren't anywhere near in line with each other.  This is why the stock muffler has that angled piece where it attches to the header.

Title: Re: New to Forum
Post by Gort on 03/15/10 at 15:37:07

SJ you are close but not quite there yet.  I ran into the same problem of the header pipe being a tight fit.  I got to where you are, and seeing the problem, made sure the muffler bracket was lined up with the Savage bracket, and then used a Magic Marker to make locater marks on the mouth of the Dyna muffler in relation to the the Savage pipe.  I then removed the Header pipe from the Savage, and placed both it and the muffler on the work bench.  Carefully bracing the header pipe from moving or bending, I re-aligned the muffler in relation to the pipe, using my locater marks.  Then, using a piece of 2X4 behind the muffer's rear exhaust outlet, I hit the 2X4 with a hammer, driving the muffler onto the header pipe ( using Pepsi can aluminum as a shim around the header pipe.).  I kept checking the alignment of my marks, and watched to be sure that the muffler inlet went over the header pipe in a straight manner.  I was able to tap the muffler onto the header pipe until the header pipe shoulder was within 5/16" of the muffler mouth.  I then clamped it tight with the Harley clamp that came with the Dyna.  Then I very loosely bolted the assembly back onto the bike, first to the Savage bracket.  I then bolted the header pipe back to the engine firmly.  I then tightened the muffler to the Savage bracket, and then put on the heat shield.  

It may be that part of the reason some members need to use spacers between the Savage frame bracket and the Dyna; or tweak one of brackets; is because of minor variances in the bracket locations from one frame to the next.  Remember, this bike frame is no precision item.  You're not dealing with a wristwatch here.  There may well be minor variations from one frame to another, in any low end assembly line product, like this one.

Well I know what I would do w/o question, I'd grab the cutting wheel, cut 2/3 thru whichever side of the pipe had to close up to line up, relieving any risistence, then grab the mig and weld it up. I would never be forcing,....knocking it on w/ a hammer etc etc ! You will just be asking for trouble somewhere down the line, all the while hoping the studs don't break out of the head, or worse.
And I'm not mechanically challenged either, been down too many of these roads before.

Thanks again Gort.  I wish I had been able to find this kind of detailed information before I started this project.  It's now clear to me that this isn't the 20 minute slip-on job I thought it would be.

I think I'm going to cut my losses and just go with the Jardine instead.  If I order it tonight, I can probably have it delivered and installed before the weekend.  These Dyna mufflers will be back on Ebay soon, if anyone wants them.

SJ!  Don't give up so easily!  You are almost there.  Its really not a hard adaptation.  Just take patience.  Think of the money you will save by using what you already paid for.  You already got the Dyna, why not finish trying?  

Or buy one of those tailpipe expander tools and open up the mouth of the Dyna.  That should allow it to slip right on the header pipe.  $13.00 at Harbor Freight and Tool:

Title: Re: New to Forum
Post by Gort on 03/15/10 at 20:05:09

Its easy to remove the pipe, and I didn't even replace the gasket and it didn't leak. If you buy the tailpipe expander, you wouldn't have to remove the pipe.  It should slide right on.  If you don't use the expander and remove the header pipe first, you won't have to worry about nonsense like "breaking studs out of the head, or worse" as was earlier posted.  Mine has been on for 2 years without a single problem, because none of the studs have any increase in stress or different vectors of stress on them as a result of the Dyna install.

Title: Re: New to Forum
Post by John_D on 03/15/10 at 23:47:41

I agree, it's a piece of cake to remove the header; I did it, and I've never worked on a bike before.  I put had a piece made to bridge the gap, to take care of the angle, and the different diameters.  Just take in the header and muffler so they can spread/shrink each end to the right dia.  Mine's about 7" or 8" long (get it long, you can always trim it down) with a couple degrees angle.  Fit like a charm, and my muffler didn't even have the rail type bracket.  Matches the lines of the bike pretty decent too.

You can go to any ACE or type hardware store and buy a small peice of brass and put it over the header to make up any differance. then make a bracket or use the stock bracket to make a new one. It does take a little intution but it is well worth it in the end I did it in 2 hrs last week end. start to finish.

Post by Boule’tard on 03/16/10 at 10:00:35

When I put on the Dyna there an alignment issue similar to what SJ has pointed out.  Two things remedied this:

1. Shim the forward heat shield's lower mount with washers and replace the asbestos pads with thinner pads.  I JB welded some copper sheet to the inside of the shield so the header would not chafe on hard metal.  Moving the forward shield a little and removing the pads allows you to rotate the header outward slightly without tweaking the header collar bolts.

2. Add washers to the rear mount (more on the front bolt, probably) so that the muffler points straight at the end of the header once the header is in position.

Almost done.  Cut two extra relief slots in the Dyna's collar so there is one every 90 degrees.  Use some thinner copper sheet to shim out your header to the inside diameter of the HD muffler. I tried beer can aluminum but it was too flimsy.. the copper was a half millimeter or so.  Once your header is shimmed, put that big ole HD clamp on there and.. after all that.. it bolts right up!   :D

Well, I finally came up with a solution that works!

I took the day off work today and headed out in search of a friendly muffler shop.   The first one refused to help me, said they couldn't work on bikes.   The second one said they'd take a look at it if I brought the bike to them, but they couldn't promise anything.   The third one tried to be helpful, but they only spoke spanish and didn't understand what I wanted even though I showed them a picture of the header pipe and brought both mufflers into the shop to show them.  I walked out with this, free of charge:


http://home.comcast.net/~siriusjoe2/try1.jpg


The last place I stopped, I had better luck.  They understood the problem, and charged me $5 for this:


http://home.comcast.net/~siriusjoe2/try2.jpg


He left the ends long so I could cut them however I wanted.  But there's still one problem with this - Even if I cut it as short as possible, the mounting rail doesn't come close to the bracket.  See here:


http://home.comcast.net/~siriusjoe2/try3.jpg


So, how did finally solve the problem, you ask?

I gave up, called Dennis Kirk, and ordered the Jardine slip-on. They're shipping it out this afternoon and it will be on my doorstep when I get home from work Thursday night.  I'll have it installed before I go to bed, and I'll be riding the bike to work on Friday if the weather holds up.

Thanks to everyone who provided help and advice, but it just wasn't meant to be.

So did mine. If you open the mouth of the Dyna pipe with a tailpipe expander tool, it will slide right in.  I didn't, and had to tap my Dyna gently to get it to fit within 5/16" of the shoulder on the Savage header pipe.  Other than that, it was an easy, permanent install.  Did yours slide right on the header without effort?  How far was the shoulder of the Savage pipe from the mouth of the Dyna pipe, when it stopped?

Ok, a simple question,
If the Dana inlet is already too big to match the size of the header pipe, (everyone says they are) then why would you make it bigger. And how does that cure the alignment problem ? Is making a hole that is already too big, being used in place of the 7-10 degree alignment problem ? Please say you're kidding ! Or tell me what I'm missing.

The Dyna inlet is not large enough to allow the Savage header pipe to slide far enough in to allow a secure fit.  You either open it up, or use enough pressure to force it on until it stops.  Various members have found that it will stop 5/16" from the header pipe shoulder. Mine stopped at that point also.  That amount is sufficient for leak proof reliability, when properly clamped.

The finished assembly angles in towards the back of the bike, as I have shown in pictures.  The angle is not that bad, nor is it 7-10 degrees off.  See the pictures.  This has been done by a lot of members without welding, or sleeves.

Post by Gort on 03/16/10 at 19:57:53

My pleasure.  

I have been here long enough to hear so many issues over this installation, that it has led me to suspect that part of the problem may be that the Savage frames may not all be made precisely the same.  A few degrees off here, and a few degrees of difference there, may add up to enough total difference to cause  people problems with the converted exhaust assembly angling back in towards the frame, too much.  Then there is the Savage header pipe end, which is sandwich sleeved and not very precisely done.  There may be thickness variations from one pipe to the next.  That may not  matter if you use the Savage muffler since it was designed to fit any Savage header, no matter how much variation there is in that pipe.  But it may matter when you try to put a Dyna over the pipe.  Also, the inside of the Dyna pipe tapers just a little, as it gets closer to the actual muffler entrance.  There is probably variation in the tapers from one Dyna to the next, since they are not precision made.  This might account for why some people can't get it on far enough.

But then there is the human factor, also.  Not everyone has the mechanical ability, experience level or patience to do this adaptation.  So who knows what the problem really is here.  For some, its easy.  All you can do is try it and see what happens.

I still don't understand this.   My header pipe is 2 and 7/16 to the collar.   The header goes a full 2 inches into the Dyna before it stops against the lip on the inside of the muffler, leaving only 7/16 left.   I don't see how 5/16 versus 7/16 makes any difference here.  2 inches of surface is plenty for the clamp.  Getting the header into the Dyna isn't the problem.    See pictures below.

This is where the problem lies, and I think it's a difference in the manufacturing of the header pipe.   On my bike, it's more than 10 degrees.  In fact, if I allow the muffler the follow the natural angle of the header pipe, THE FAR END OF THE MUFFLER IS BANGING AGAINST THE REAR WHEEL HUB.   The rear end of the muffler needs to be bent out to the right about 4 INCHES before it will line up with the support bracket, and this puts stress on the exhaust pipe and the flange/studs.  (Not to mention the fact that you can only get 1 bolt into the support bracket.)  


http://home.comcast.net/~siriusjoe2/bs3.jpg


This muffler WILL NOT fit properly or safely on MY bike, and I can easily see why it doesn't work for some other people too.  

Now, I've already found a solution to my problem so I no longer have much interest in this.   But for the sake of all the future newbies who might stumble into this mess like I did, please start attaching some disclaimers to the whole "bolt on a Dyna muffler" mantra.  It doesn't "just work" for everybody.

You're welcome.  No problems getting it made, once I went to a small "Mom-n-Pop" place.  Mine cost more though, a wopping $12. ;D
I think the problem you're still having with spacing is due to the difference in the bracket on the muffler.  Mine was a generic muff without the slide style bracket.  I have one bolt in the rear of the bike bracket into the front muff tab, which is farther forward than the slide type seems to go:

You could probably still make your setup work, just get a piece of strap iron, bolt it to the bracket on the bike to extend it back, then drill a hole or two to bolt the muffler onto.  Has anyone else done something like that, and did it work? :-?

Title: Re: New to Forum
Post by Gort on 03/17/10 at 11:52:27

Here is how mine fits in relation to the rear wheel.  It is close to the brake cable but doesn't rub it.  The Savage header pipe is 5/16" from the mouth of the Dyna.  Everything bolted up.  

These Dyna's cost close to $30.00 off Ebay and less from Harley shops that remove them.  They sound good, and can be made to sound louder. Myself I think its worth the try to see if it can be fitted to a Savage, in light of how easy it has been for so many owners.

Yes, the mounting rail on the Dyna is toward the rear.  It would be better if it was nearer the front, or if the muffler was a bit shorter overall.   Maybe the Sportster muffler is a better choice, I don't know.

Yes, I think I could, but the idea of bolting on even more stuff to make the bracket fit was the straw that broke the camel's back.

Like Routy said earlier, either the part fits or it doesn't.   This one doesn't, so I bought one that does.  I'll be happy to report on how that installation goes, if anyone's interested.

I will be curious to see how well the Jardine bolts on, and promise not to laugh if it also requires a little "encouragement."

Ok so you got an 05 model.. any signs that the bike was tipped over on the right side?  Because if the previous owner dropped it and tweaked the rear mount, that would explain why the rear of the dyna muffler was too far left for it to go on.

It's an '06.  No signs of damage anywhere on the bike.  I checked every inch of it before I bought it.    My wife and son both ride this bike, so I'm very cautious about safety issues.

Rear mount seems to be in the right place, judging by pictures other people have posted.  Doesn't appear bent or twisted.  

I'll let you know what happens with the Jardine.

At any rate, when I look down along side my bike, I see a kink of enough degrees that I would never attempt to install a "straight" muffler, no matter how many people say it fits ! I guess it could all be in the definition of "it fits" ::)

There's no contradiction there, if you think about it.  You can give the pipe an offset from the rear mount that requires the bend at the inlet (Jardine) or have less offset and no bend (Dyna).  Any angle/offset pair can be used as long as the trig works out.  The stock muffler has the angle because it's such a fatty.. the muffler's radius makes for a large offset.  

The Jardine slashcut does look pretty sweet, can't argue with that  :D

Pretty much. Mine is an '05 model.  Like I said, the header is rotated out slightly and the lower mount of the forward heat shield is shimmed right to accommodate the header.

$162 at Dennis Kirk, no tax and free shipping.  I ordered it Tuesday afternoon, and it was sitting on my doorstep when I got home from work today. (Thursday)

Installation time was approximately 10 minutes.   All I needed was 2 sockets, 1 screwdriver, and 1 clean rag to polish it when finished.  

Bolts, clamps and heat shield included in the box.  Box packing quality was excellent, with plenty of protection for the chrome.

At idle it's a nice rumble.  When you crack the throttle, it's loud.  The baffle in there is pretty minimal.   It might be a little too loud for my wife, but my son was grinning from ear to ear when we fired it up.

I'll try to make some sound recordings this weekend.  I know there's one already posted here somewhere, but I don't think it's a very accurate representation.

For the quality and the ease of installation, I think it's a fair price.  It's a well-engineered product.

I'll probably hang on to the HD muffler for a while.  I think I can make it work if I modify that custom angle adapter a bit, and the Jardine may be too loud for my wife.  We'll see how she likes it after a few rides.

Both of ours were an easy install.  Mine was a bolt up, no welding or drilling or adapters.  It has a  rail welded to the side of the muffler, by Harley. You can see both mine and Jabman's pics earlier in this thread.

These are often on Ebay, or at Harley dealers for dirt cheap.

Sportster, Dyna,.. l
look for a rail mount, not a tab mount,... no crossover tube,... and not de-baffled, if you want reasonable volume level... de-baffled, might as well be straight pipe...
