Superior Design. There is a pleasing aesthetic symmetry between the retro chambered mufflers and the clash-cut tips of the Stainless Works 3 in. retro chambered cat-back exhaust. Maybe one day, designers will realize this and put exhaust systems on the exterior where they can be suitably admired. Until then, we have to accept that the catalytic converter needs to be directly adjacent to the engine, where it derives sufficient heat for activation, and leave the artwork in the Pony's underbelly.

Premium Construction. Many exhaust manufacturers are satisfied with garden variety S304 stainless steel. Its high chromium-to-nickel ratio (18%/8%) give it the strength and rust-resistance it needs to be fit for purpose. Stainless Works prefers to take it up a notch with Everlast 304 stainless steel, a military specification that simply will not rust or discolor.

Pleasing Noise, Gusting to Aggressive. Whatever the weather, whatever the road, the Stainless Works 3 in. retro chambered cat-back exhaust delivers a pleasant rumble at idle and at cruising speeds. Crank open the accelerator, and the sound becomes louder and more aggressive, but never oppressive, never a drone.

Installation. Direct-fit, drop-in upgrade. No modifications required.

Warranty. Materials and workmanship of the Stainless Works 3 in. retro chambered cat-back exhaust are covered by a limited lifetime warranty.

Application. The Stainless Works 3 in. Retro Chambered Cat-Back Exhaust has been designed and implemented to fit 2011-2014 Mustang GT with Long Tube Headers; and 2011-2012 GT500 with Long Tube Headers.
