TSP Rumbler vs. LOUDMOUTH

[MIKE M]

are these both about the same thing?? and is it much different than just puttin dual pipes from the cat?? anyone know the specific power gains from each??

They are very similar, but the Rumbler has a bullet muffler in the I-pipe instead of a resonator. This cuts down on ALOT of rasp and "ricey-ness". Power gains will vary, my 6 speed car with a cam and headers, no cat picked up 10rwhp and 12rwtq OVER the open cutout and stock catback.

Is rumble legal in all states, I'm just wondering if I get I would not pass emission?

[OneQuickV6]

I'm not sure on that one to be honest with you. Your best resource for that information will be other car nuts near you....they can help you with finding that certain shop that will pass your car if need be:)

[C.O.Jones]

It should pass emissions as long as you don't dick with the cat. Noise emissions... well that's another thing.
