Porter Mufflers releases its first complete cat-back exhaust system.

PORTERPorter Mufflers is proud to introduce its first complete cat-back exhaust system for the 2009-13 Dodge Challenger 5.7 HEMI. This system 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 pounds of weight from the car. The Porter Mufflers give off a deep, mellow rumble at idle with no drone when in cruising mode so your drive is more enjoyable.

“We are quite pleased to offer our first complete exhaust system for the new 5.7 HEMI Challengers and we targeted those customers that want a performance system upgrade that screams at full-throttle but is still mellow at idle and cruising speeds. This system does that and at a significant pricing advantage” says Tom Conlan, owner of Porter Mufflers.

Challenger owners no longer have to choose between real performance gains and every-day enjoyability with the Porter Exhaust System. It’s build to perform, built to last, and made right here in America with American-sourced materials. MSRP $849, see for your local dealer.
