Well I want to get an HMF slip on exhaust but the thing is do I really have to get it jetted from just adding on a slip on? What will the affects be if I don't get it jetted and what are the benifits from jetting it? Also will you notice a differance from the pipe?

 

yes u do. mine ran like sh** when i put it on with out jetting it. pipe it jet it and good air filter. then hang on...lol

 

Why not rejet dude? The change in exhaust needs the adjustment in the carb to do any good. Rejetting is not as big a deal as it seems.
