It ain't whistling dixie no more.....
Or....it doesn't sound like a old VW bug any more either.

I was told it sounded like a ATV (ouch!!) and another "friend" said it sounded like his Dad's old Beetle (I admit that it did sound like that whistle the old VW's had just over idle and at a easy cruise speed. )



Had a day off (had to burn up vacation or lose it) so mounted the Dyna muffler I got on Ebay.

It's a little louder than I wanted but it does sound better.

It "sort of" bolted up.
 I didn't get any mounting hardware with the muffler so I had to make a threaded piece to slide into the Dyna muffler mounting bracket to act as a nut.  I used a piece of flat stock steel 1/4 "(zinc plated) and drilled a hole and ran a tap thru to fit the bolt I had.  The stock doughtnut exhaust gasket was too thick so temporarliy used aluminum foil that I folded over several times and then wrapped around the header pipe (not sure where I'm going to look for gasket material).   I reused the factory heat shield so I had to make a bracket to hold the back of the shield (normally mounts to factory muffler).

Here's some pict's of the mounting .

Performance ? ? ?

Stock'01 pilot jet, and a 150 main (thanks Lancer) with white spacer mod using washers (three metric washers from an old computer (hey, it's a good use for for the old clunker's)). Adjusted the pilot screw after warmed up, also had to adjust the idle a bit.

Well,... when rev'ing the bike it does give some black puff's....but it didn't get black when running.  Actually is a nice gray color.   I think the puff while rev'ing is the fact that the slide is not perfect and doesn't get down fast enough on a quick rev.  

Back fire? ? ?......only if I get on it then let off otherwise it does not back fire on deceleration.  It is much more throatier on deceleration.

acceleration:  Hard to say....but I do notice that it seems better when I lug it (2K rpm's on the tach).  Before it sounded like it was almost pinging or knocking....

Other than it's a bit louder than I wanted,  I am happy I did it.

i bought the heat sheild from jc whitney and it looks great. i think it was 20 bucks. mine is louder than i wanted too but sounds way better than stock.

Oh, if it's any consolation, when a stock exhaust sounds like a whistling VW, that's a good thing.

Why?

Because when a VW engine whistles, that means it is actually tuned properly

nice job! i mounted my exhaust with a car clamp, for good reason too, i need to fix the motor, but cant run it when it was straight piped (stupid sound laws)

Nice looking pipe & install. I'm wondering if you looked through it before putting it on, to see what kind and how much baffling it had in it? I ask because I've got a similar looking turnout style muffler, except mine has about a foot of straight pipe before the muffler. Mine is really loud! So loud that I didn't leave it on but a couple of hours. I don't want a pipe so loud that it makes my ears ring when I wear my shorty helmet. So anyways, I looked through mine, and all it has is one little round tab of metal sticking up from the side wall to act as a snuffer, and that's all it has for baffling!

You say your turnout is a "Dyna" but I have the straight type Dyna muffs on both of my Savages, so is yours a Screaming Eagle, or just a different model Dyna muffler? I'd sure like more details on exactly what yours is...?  I sure wish there was some way for all of us to quantify how loud our pipes are, short of everyone having to buy a sound level meter!

Thanks for the info on the rack. You do very nice work!
I had a '70 Honda CB750 with a sliding back rest on the rack, so I should have noticed the look.
You have made something stronger than anything I've seen on any Savage.

Thanks,

Rockin John,
  Sorry I missed your questions.  

Yes, the muffler you have sounds exactly like mine.  Little tab sticking down and side wall acting as a baffle. I really like the look.

It was advertised as a Dyna muffler.  BUT.....I think it's a aftermarket muffler because the stamped on EPA noise warning does not  say Harley anywhere.  HD likes to put their name on things when they can.

Loud, yes....I wear a open face full helmet so it's a little deadened.   I tried to add some stuffing to make it quieter.  First used some Stainless Steel "steel wool" from the grocery store.  It was too thin and couldn't take the heat.  Lasted about 10 miles.  Monday I took it apart and tried taking some copper wire and wadded it up in the front. Couple of feet of it (14 gauge, solid, old house wire, ...Yes it was tedious to strip the plastic off).   I'm pretty sure it won't last but it is a little quieter.  SO, I have learned that I can add more baffle and it does get quieter.  Maybe next would be getting some steel pipe and drilling a gazillion holes in it.  It would take the heat.   I figure the sum of the area of the holes should be equal to or greater that the diameter of header the pipe.  The added  turbulence should cause muffling.  I just have to get motivated.

A comment:  I do notice that I'm shifting earlier to keep the the noise down.  Only jump on it once an a while.  Maybe I'll get better MPG.........keep wishing.....too much fun watch the HD riders do a double take.

I put on a similar turnout (screamin chicken something or another............) and the only baffle was a perforated piece of metal set at an angle in the main bore.  I fabbed up a baffle to put a cross piece directly inline with the headpipe.  I cut and bent a piece of tubing so that there is a 1-1/2" round piece for the sound/gases to hit and hafta go around.  I may eventually get a baffle, but I did this while it was still easy on and off.  I tried posting some pice but had trouble.
