Hooker cat back or flowmaster catback? Does the hooker flow better? What could be causing exhaust odor inside the car? Leaky headers? Any ideas?

flows are pretty restrictive... but they have that bad *** sound to them... i'd go with the hooker cat back though. and the smell... you smell gas, or exhaust? if it's gas, could be a clogged cat or your running rich. if it's an exhaust smell.. well... you probably need to replace your header gaskets or check for leaks on the piping

I'd go with hooker. Flows sound like a$$ and everyone has them, especially mudstane owners. Just my $.02. but it is proven that flows don't flow at all, so hooker would be better flow wise.
