I think that having to rejet after fitting an after-market exhaust is a good thing, it means you are getting more air flow and air flow = HP.

Was just trying to help ... your previous post said:

Since you said you had never heard of any members of any forums using the MAC pipe, it seemed to me that you had not seen those posts on Heise (irrespective of their quality), and perhaps had not done/did not know how to do a search on Heise.  I was only trying to help. Good luck with whatever pipe you end up with.  Ride on!  8)

Well, not that I wouldn't like to hear your report (because I'm looking at buying a new muffler to replace my stock) but just so you have the option, I saw this like new stock exhaust on eBay (current bid at $56).  Just a thought since you said you liked the original.

Yep, you were right too!  There doesn't seem to be much useful experience posted on the MAC.  Will be curious to know what you end up doing.

However condition inside of those will always be unknown. The gamble in that is ending up right back were you were. Just because a exhaust is a low mileage take off does not stop the interior deterioration thats going to occur once that metal is heated up very very well and its coatings burned off and it in fact probably deteriortates faster when hung up in some garage or shed for a few years and never having the moisture burned out of it on a regular basis. Which I believe is what caused the early demise of my stocker. Not enough use. I suspect that is partialy to blame here. The bike only got ridden once a month and perhaps went a few months in between if not all winter without being run. And this allows rust to build faster than a regularly used bike.

So one would wonder if he was going to get a good interior pipe used. Even the seller has no way to know. He assumes it still is good. It was when he took it off. But its not in a state of hibernation. Rust is doing its thing. Always. Because he can only examine the outside he has to assume its still like it was before he replaced it. In fact it is not. Same as where mine looks almost mint outside... its coming apart on the inside. Probably from low use of the bike I would guess.

So.... its a gamble to buy a used one. And to pay almost what a performance one would be that is known to be unused. I mean getting a used one for say 70 - 100 bucks is about what one can go performance and new for. So unless you could get one for like <50 it starts becoming a delema and pricey gamble.

So what happens here is a person with a bad Muffler has only a few choices. Go to Suzuki and buy an OEM stocker for an unGodly high price. Rediculous actually. Or take a chance on a used one.... or go performance.

And certainly I see absolutely no resonable level or market for a aftermarket "stock" type of muffler. I wouldn't make one either. I mean how many would you sell? maybe two or three a year? If that many. No way if I was a manufacturer would I consider it. And funny thing is most of the manufacturers out there barely see any market for Savages ANYWAY for ANYTHING... so....

Cool! I am very interested in what you first impression are of the workmanship. Might help me decide. That and watching and thinking on used ones.

I should ask my spouse if she wants to sell hers.

OK Update....

There was a message on my cellie... this morning from the dealer said he got one of these in. And wanted me to look at it and see if I wanted it.

So I tootle down there this morning when he opens and takes a look.

We open the box. and its rather much a straight shot with some baffling around the edges. Chrome looks fairly well done. Hard to tell about new chrome. There was a little dimple/dent in this one. Not what I would call bomb proof packing at all. But so he says "well... if you want it I will knock off some money for it. If not no biggie, I just knew you might be interested and figured I would just go ahead and stock one". So I asked him if he was going to return it or something and he just shakes his head and says "well thats just more trouble than its worth. Trust me I have returned stuff before and its just not worth it. I'll just sell it cheap if need be rather than that". Seems all this comes from a Distributor, not factory direct stuff but a wholesaler. So I said well "how much then". He says "ok.... $75 and thats what I got in it. So I agree. Needless to say its already "pre-dinged" for me....   But hell its cheap right? So I bring it back here and go to work....

Now let me tell you this thing is little more than a straight pipe with some shape and some baffling around the outside. About half the diameter of the Original stock one.


First thing is to get the old one off. So I go about that. If you have not done this before (like me) it takes you a few minutes before you discover that the two Header bolts are going to need to come out so the up pipe can move a little bit to let the two rear mounting bolts clear their mount on the swingarm bracket. Once you do that it all slide off pretty easy. And leaving them lose to refit the New muffler is of course a good idea as well.

Now the fit:

Well it does not fit as good as Stock. Naturaly.  Its not really made exactly with the same angles and in the case of the back two bolts to the swing arm they did not bother to wedge shape this like the stock one. So at first it seems its going to fit awfull. And you might be temped to quit on it right there. But by leaving everything lose and tightening things a few turns at a time, First center clamp a tad, then two head bolts down to snug then two rear swing arm bolts half way. Wiggle and rotate a bit.... continue to alternate tightening each thing... and it sort of works its way into where it wants to be and things start to draw into place and come close to decent. Not perfect. But pretty darn much closer than you would first thing it was going to. Doesn't look too bad at all when if all finaly cinches down. In fact pretty decent.

Now the issue of the stock heat shield. Well they put one tab on this thing and the stock one had a double screw attachment and slide in bracket. There is not very much to hold it to. And its in a location that if you don't put it on first before you slip the new muffler on you cannot tighten a screw very well. So that small single screw should be changed to a hex head machine bolt if you do this. What I am doing now is that. I did manage to get the screw in and with an offset screwdriver get it snugg but not what I would call secure.

Now that stock Heat shield is a bit large for this new smaller diameter muffler. It probably should be changed to a more flush one of some type. You might like it you might not. I will show you a picture of that soon....

Took me about and hour. Would have gone quicker if I had ever done one before. But I was carefull and deliberate. And I still will need to do some snugging now and recheck some torques today.

Now to sound. THIS THING IS LOUD! I don't care what he said its loud. The funny thing is it may not be any louder than any other out there because I have no reference to say. But it does GROWL at you. I mean a VERY MEAN AND NASTY SNARL.... and at idle you can really hear where these big singles got the nickname Thumper. It does indeed now thump thump thump.... I don't know if its obnoxious. Again I am a quiet kind of guy. However oddly enough my wifes first comment was "now it sounds like a motorcycle". Now go figure. She says she likes it. She says she could never hear me pull up before and it soulds like any other motorcycle now. So well.. if chicks dig it.... erm....  8)

So lets see.... I just don't know at this point. I did get a tad more backfire this morning after testing it out. Not much. Maybe I could just hear those little ones more. I dunno. Not rode it enough to really be ready to comment on those.

Let me get some pictures up... Hold on.

(I am NOT out of the market for a stocker cheap. And I did, after take off of the old one find a crack near a weld in the rear of it. Probably where my noise was coming from. Not certain I can weld it though)
