I agree Austin. The 3" would have only made it louder and robbed low end torque. Im not turning 5,000 + rpms and it'll be loud enough as it is. If it were 500+ hp, both comp cams and my builder would have suggested 3".

Trying to get all the systems in tune without over doing it isn't easy. Exhaust and cams are common places where guys go too big.
