cat back will replace the stock h-pipe with an x-pipe.
Ok.
Thank you. I'm learning
So when looking to buy a full exhaust, if I buy headers with hi-flow ehxuast, and an Xpipe....then I should be looking for an axle back exhaust....not a cat back exhaust...right?
Is this how it flows: Headers to cats to xpipe to mufflers?
Cat back is exactly as it states, from the catalytic convertors back. The problem is that many Vendors (and lots of private sellers) either don't know or intentionally lie and call their axlebacks a catback.
Stock C6 exhaust is in 7 pieces, L & R manifolds (or headers), L & R cats, a mid pipe and L & R overaxle pipes w/mufflers and tips.
