yes.

What is your budget? Where do you live? Do you have headers?

The dream exhaust:

1) Long tubes
2) Bullet cats (2)
3) x-pipe
4) conventional dual exhaust

This will pass any sniff test and add 30+hp to your motor.

The downside - it will NOT pass any visual inspections.

Iam with Bogus, period. If u have $$ call Random technology recently they came up what Bogus is talking, Dual Cats+pipes+X-pipe. 350 ? Rwhp or at crank. If its 350 RWHP than defenitely Headers+Dual Exhaust +Dual Bullet cats + X-pipe + 2.5" Mufflers (ur choice borla, corsa, etc or custom).
