catback

An exhaust system that allows the exhaust gas to exit, while reducing back pressure. They use larger diameter
pipe than standard pipes.

"I just put catbacks on my Mustang, it's going to beast ass on all those civics and 'yotas out there."

Catback-Style

A sexual position similar to doggy-style where the woman kneels with a flat back and forces you to thrust at an unnatural, upwards-diagonal angle much like the way cats perform intercourse.

A relation has been found between the amount of cats a woman owns and the likelihood she will attempt this horrendous sexual position.

Man: "Why are you kneeling in this uncomfortable position? this isn't doggy-style"

Woman: "What are you talking about?"

Man: "You must own a lot of cats.. I hate Catback-Style"

Catback

A catback exhaust is an exhaust system which has catalytic converters still in place. It refers to the components that run from the rear outlet of the catalytic converter all the way back to the exhaust tip.

I prefer a catback exhaust over open headers, which are too noisy.
