Looking at replacement exhaust for a GSXR-1100G


I'm trying to resurrect my 1100G - due to poor storage, the exhaust has expired - well, after I got the engine started, the exhaust spat all sorts of rusty bits onto the ground, and has a lot of extra holes to let out the exhaust gases. (Everything else on the bike is pretty good, but the carbs need a good clean and the front callipers needed a rebuild.)

The original exhaust is no longer available (which I am sure you all know).

I think there are the following options:

1. Find someone to cut off the old muffler, and weld on suitable bits for a slip-on muffler. The downpipes are OK.

2. Buy new aftermarket exhaust system

3. Search classifieds and hope

My worry about 1 is performance - will it need some form of retuning/rejetting? (And is it actually doable?)

The problems with 2 are:

a) cost
b) availability - I can only find two viable complete street systems - Cobra and Barracuda (from Germany). Yoshimura has a race system that I can get in Australia, but the website talks about needing fairing alterations - I still have the original fairing fitted, which is in good condition.
c) legality - It needs to be street legal in Australia (Victoria) and I don't know how I will go on a personal import system from Germany.

I'm not keen on 3 - time, and inheriting someone else's problems.

Has anyone had experience replacing the stock exhaust? Which way did you go? What systems did you use?

Biggest issue is fairing fit. Typical interference on the front v cross member and staying abovethe bottom of the fairing. The 1100 and 750 shared the same aftermarket pipes so I doubt tuning is a huge issue. Fitting a aftermarket muffler collector would probably save five pounds but needs a bracket fitted.

Re: Looking at replacement exhaust for a GSXR-1100G

Thanks remusr. I want to avoid fairing mods.

I think that only the muffler needs replacing - but this then becomes a cut and weld process to add the right bits for an aftermarket muffler. It also needs a skilled welder - not me :-) .

Iíve been tied up with our kitchen reno this past week, so havenít had a chance to look into it much further.

Regards Rob.
