Have a question for all out there - I bought a full Kwaka 4 into 1 exhaust system in top condition at a garage sale, didn't know what machine it was off but I wanted the Can to modify for the ZRX1100 - the headers and pipe are of no use so if someone can tell whan machine they are off they are going cheap. The number stamped onto the Can is "KHI K 380" and the number on the pipes is "KHM M 049". I know that these are not the numbers listed in parts catalogues but they may be on the pipes of yours or a mates bike. Let me know if you can help.
Cheers, lenno.
