As a singular mod to the exhaust system, I'm skeptical that you'd
get much "seat of the pants" gains from most catbacks. The hp gains
seem minor in context and beyond that alot of people i've talked to
feel the numbers most/some manufacturers put out there are optimistic
Sure, if you're going to do a full front to back low restriction pass
on your exhaust system you'd want to open up the catback, but viewed
as an isolated upgrade, i think the biggest thing you get is a different
sound out the back of the car.
