Rejet?

[mikeb1978]

I have a 2005 600 and Im putting a D&D exhaust on, do I have to rejet after its on? Thanks

Just a slip-on? No, you don't HAVE to rejet, but a jet kit isn't a bad idea. A full exhaust system? Yes, you need to rejet.

Jet kit is one of the best upgrades for engine performance from these bikes, even with a stock exhaust. Do you need it in your situation? You already have that answer
