Hey guys, i keep hearing about catbacks, what exactly is/are it, Ive heard of a just a FULL catback system and like DC Sports Catback, what do they do, and is the power increase noticible in a automatic? thanks guys.

cat= catylitic converter, back= until the exhaust fumes leave the exhaust. A cat-back alone will not do a lot, but when combined with a header( it replaces the exhaust manifold) and a cool air intake, will.

 

when someone steals your cat and you get it back

 

it's basically the thing that makes your car sound buzzy like a bee! and yes it will give you power, but don't expect mirracles, it's an accord!
