Porter Mufflers' cat-back exhaust system for the 2009-13 Dodge Challenger 5.7 HEMI is made up of 2.5", mandrel-bent 304 Stainless Steel tubing, uses the original hangers and tail-pipe tips, and features Porter's unique "Steel-Pac" mufflers, also in 304 Stainless Steel. In chassis-dyno testing this system provided a 12+ horsepower increase while dropping 28 lbs of weight from the car. The exhaust gives off a deep, mellow rumble at idle with no drone when in cruising mode so your drive is more enjoyable. It's built to perform and last, and made right here in America with American-sourced materials.
