Stainless Works 2011-14 F-150 3.5L 3-1/2in Catback S-Tube Muffler Factory Connection

Stainless Works is known for building well-made exhaust systems, and this 3.5-inch cat-back system for your 2011-2014 Ford F-150 with the 3.5L Ecoboost engine is no exception. If you're looking to give your truck a more aggressive sound and potentially improve exhaust flow, this kit is designed to connect to your factory exhaust setup. It's built for trucks with wheelbases up to 156.5 inches.

This system is constructed from 304 stainless steel, which is a strong choice for resisting corrosion, especially in areas where road salt or moisture is common. All the tubing is CNC mandrel bent, meaning the bends are smooth and consistent, which helps the exhaust gases flow efficiently without restriction. The S-Tube Turbo Muffler is specifically designed to manage sound while still allowing for better flow than the stock muffler. For added strength and durability, the entire system is TIG welded, a process known for creating solid, long-lasting joints.

When you get this kit, you'll find it's made right here in the USA and comes with a lifetime warranty, which speaks to the confidence Stainless Works has in their product. Everything you need to connect to your factory exhaust point is included, making installation as straightforward as possible for a cat-back system.
