Stainless Works 2015-16 Ford F-150 2.7L/3.5L 3.5in Catback S-Tube Muffler Factory Connection

If you're looking to give your 2015-2018 Ford F-150 with the 2.7L or 3.5L EcoBoost engine a more aggressive sound and better exhaust flow, this Stainless Works cat-back system is a solid option. It's designed to connect directly to the factory flange, making installation more straightforward. This system replaces the factory muffler and piping from the catalytic converter back, changing the overall tone and performance of your truck's exhaust.

This cat-back system is constructed from 304 stainless steel, which is known for its strong resistance to corrosion, meaning it should hold up well over time, even in harsh conditions. All the tubing is CNC mandrel bent, which helps maintain a consistent diameter throughout the bends. This ensures optimal exhaust gas flow, which can lead to a slight improvement in throttle response and a deeper, more satisfying exhaust note. The Turbo S-tube muffler is at the heart of this system, designed to provide a noticeable sound change without being overly raspy or droney. It's finished off with a polished tip for a clean look under the truck.

The system is TIG welded for strong, durable joints that can handle the stresses of daily driving. Because it's made from 304 stainless steel and built with TIG welds, Stainless Works backs this system with a lifetime warranty. It's also proudly made in the USA. This kit is designed for F-150s with wheelbases up to 156.5 inches, covering a wide range of the 2015-2018 models.
