Aftermarket exhaust kits and mufflers have been developed for several reasons. Most of the performance guys will add these kits to their vehicles to gain horsepower, usually adding 5-15 additional horses. Another good reason to upgrade an exhaust system is to increase your gas mileage, as your engine tends to breathe a little bit better with a new exhaust. With gas prices reaching new highs this summer, that alone is a good reason to upgrade your exhaust. One more reason why guys change out their exhaust is to have that cool growling sound when driving. When it comes to exhaust systems, people tend to have different tastes.

Rumor has it that they're already working on the next generation of Impala kits, so watch out for those. For this article, we caught up with The Muffler Man in Placentia, California, who was installing a Flowmaster mandrel-bent exhaust kit on a "first generation" Impala. This kit was a long time in the making and comes with a few muffler choices, including a short version and a complete tube kit. For this install, we opted to use a complete system with two Hush Power 2-inch mufflers. You've seen them advertised in Lowrider as the "Sound of Lowrider," and Flowmaster has pretty much hit it on the dot with their all-steel mufflers and exhaust kits.
