if you get a better exhaust does that mean you have to get a better intake so it can breath better, or is there nothing you have to do when changing exhaust
you can do one or the other, but best results will be when you do pipe, intake, carb and A/M filter for a complete package
and yes there is one other thing you need to do when changing any of the above....
REJET your carb to match the incresed airflow !!!!!
if i get a carb and exhaust i am going to need more and and i cant take the lid off cause i got through water and mud with my blaster and the lid protects my air filter
