Has any one got one? Done a search and found one chap who fitted one , but than send it back and thats about it. Is it worth having one without changing the OE system or the improvement is in conjunction with a new end can and headers?
Fitted one to my 09 GS last week, wow what a difference, engine is definately more urgent & less asthmatic.
So far its prob the best mod Ive done, just makes the whole bike feel connected.
Would recommend it to everyone.
