Stainless Works FT15ECOCBLMF EcoBoost 3.5" Cat-Back Exhaust S-Tube Muffler Factory Connect

The Stainless Works FT15ECOCBLMF is a 3-1/2" single-exit cat-back exhaust system engineered for the 2015–2020 Ford F-150 equipped with the 2.7L or 3.5L EcoBoost engine. Designed to connect directly to the factory flanged connection point, this system delivers an aggressive exhaust note and improved exhaust flow with a true bolt-on fit.

At the heart of this system is a Turbo S-Tube muffler, tuned to produce a deep, throaty sound profile that complements the turbocharged EcoBoost powerplant. The system exits through a 3-1/2" polished slash-cut tip for a clean, purposeful appearance.
