Is it worth spending money on a free flow exhaust? I have a new to me 350 XCF-W and would like to know if it makes a big difference. My Zeff side wants it for the sound, but does it improve performance?
I also have an FMF power bomb, not fitted, do they really make much difference?
Does the FI adjust itself when you fit these things?
So which one to get/not to get?
