If your planning on just doing a slip on exhaust you CAN run a bigger jet (IF YOU WANT).... if you also put a high air flow the question remains... are you going to need to run more rich...yes... because you are allowing the air to go out quicker (less restrictive) you are going to have to feed it more fuel..... more fuel....more power... also what exhaust are you looking at??? also what year is your quad???
