Re: A couple of ?'s
in regards to the cat..... it will let the motor breath with less restriction. with ouut the cat it will be much louder than if you had duals and a cat. if your not running any mufflers then you will loose some back pressure and potentaly some low end power. however as long as your piles are long there will be no harm to the motor. any ideas on mufflers and pipe size? flowmaster super40's sound great in my opinon. as do two chambers but two chambers have more in side drone
