For maximum performance, a complete head-to-toe aftermarket exhaust system—headers, catalytic converter, muffler, and tail pipe—is the way to go. A less-expensive option is to retain the stock manifolds, but go with a cat-back (catalytic converter to tailpipe) aftermarket exhaust system.Typically cat-back systems consist of replacement mufflers and tailpipes designed to reduce back pressure. As a rule, after- market cat-back mufflers are a redesign of stock mufflers and are usually found in kit form along with larger-than-stock tail pipes that are specially bent to eliminate kinks or other exhaust-flow restrictions.
Cat-back exhaust systems are designed as stock replacement parts.This is a real advantage for the do-it-yourself, as such systems are direct bolt-on equipment that usually retain the factory mounting locations and pipe muting.
A cat-back system is significantly cheaper than a header-to-tail
pipe system. Though the rewards are less, the vehicle will still perform better than stock.
