Yes, there have been some posts here about getting free Harley mufflers from dealers. Most Harley buyers add aftermarket pipes and many leave the stock exhausts at the dealer. I can't remember who posted it but one person said the dealer pointed him to a huge pile and said 'Help yourself'.

I think that was Planecrazy Steve, Joe. And it was when I was looking for a replacement for my ejected muffler. I also had a HD owner at my PT job offer me his stock pipes.

You might have to get creative (i.e. adapting the Harley Muffler route). I searched high and low for an aftermarket exhaust when I bought my GK and I am convinced nobody makes one. They are very hard to come by at the junk yards too....I really wanted to keep mine stock so I finally bit the bullet and ordered a new one from bike bandit (it was big $$$, fortunately I only needed the right side). If you (or any GSer) ever comes across a company that makes an aftermarket exhaust for the GK PLEASE let us know

[raynardton]

thanks for your help guys. Sounds like I'm going to have some trouble finding what I need. I hate to buy expensive, new exhaust on a bike that has 98K on it, who knows how much longer life the motor has in it, even though they say that the GS motors are bulletproof. . . .we'll see

how far are you from montreal?

i have a 4:1 kerker that may or may not fit your bike.
its brand new, but ill let you have it for cheap if it fits.
its originally for an aircooled gsxr750, and i got it for my 1100 but im installing a supertrapp instead so i won't be needing it.

my supertrapp will require some adapting, and im sure the kerker will as well, as far as i can tell it's just widening the holes on the mounting flanges so the bolts line up.

if you pm me your email, i can send you some pictures. if you can bring the bike to me, we can try the pipe on to see if it fits.

just an idea, you'd have a brand new exhaust (installed) for cheap.
i dont think you'd even have to rejet much, it's a freer flowing pipe than stock but its designed for a smaller engine.
i had done a similar mod on my 750 and i didnt need rejetting...

The GK pipes and E model pipes aren't interchangable. The bends are all at wrong angles and places as the GK has a different frame and engine mounting. I know becasue I once bought GK pipes for my E model.

yeah, i got surprised with that myself when i gave my stock 1100e exhaust to someone for his 1150. lucky, someone told me about while the guy was in transit from ottawa and i was able to spwap exhausts with my buddy. the lister drove back to ottawa with 2 1150 exhausts.
but i wasnt offering my 1100 exhaust, as i suspect its somewhat clogged.
do you know if the kerker 4:1 for the gsxr750 will fit?

im also wondering. if the header is good, you could just have a muffler shop bend pipes to replace teh rotten bits and adapt any muffler of your choosing...

Ron, you might PM "focus frenzy" (Leon). He and I were discussing this a couple of weeks ago but I honestly don't remember the company name he gave me. Probably not cheap though.
