This catback not only sounds great, but also improves exhaust flow with the included Y-pipe for an increase in rear wheel horsepower and torque.

      Stainless Steel Construction. Constructed in the USA from mandrel bent full 3" diameter 304 stainless steel tubing for strength and superior corrosion resistance, this Stainless Works Mustang Cat-Back exhaust system features two round retro chambered mufflers that end with mirror polished 304 stainless steel slant cut resonator exhaust tips.

      Direct Fit Upgrade. This Stainless Works Mustang Cat-Back with Y-pipe includes all the hangers and clamps needed to bolt straight up to Stainless Works Performance Down Pipe without any modifications required, making it a direct fit, bolt-on replacement upgrade.

      Application. This Stainless Works 3" Retro Chambered Cat-Back with Y-Pipe is specifically designed to fit the 2015-2020 EcoBoost Fastback Mustang without the Active Valve Exhaust and will require the use of a Stainless Works 3" Performance Down Pipe in order to be installed properly (see drop down option above). Not compatible with convertibles.
