Overview

Improve the performance and sound of your 2011–14 F-150 3.5L EcoBoost with a premium catback exhaust system from Stainless Works. This 3-1/2" exhaust system features a turbo muffler and is engineered to create our distinctive growl and rumble.

Choose your sound level with either a chambered muffler for a classic muscle car tone or S-tube straight-through muffler for a more aggressive, free-flowing sound profile. This system includes tailpipes, hangers, and clamps, and features a single 3-1/2" polished slash-cut tip.

Built from corrosion-resistant 304 stainless steel and TIG welded at our state-of-the-art facility in Streetsboro, Ohio — engineered for long-term durability and performance.
