Unleash the full potential of your 2011–2014 Ford F-150 3.5L with the Stainless Works 3-1/2in Catback S-Tube Muffler System, engineered to deliver both aggressive tone and maximum flow. This performance exhaust system is designed for those who want a bold, straight-through sound profile and improved horsepower, while retaining a clean and refined look that matches the F-150’s rugged styling.

This high-quality catback system features an S-Tube straight-through muffler, offering a more aggressive exhaust note compared to traditional chambered mufflers. Constructed from 304 stainless steel, the system resists corrosion and maintains strength over time, even under harsh conditions. Every piece is TIG welded for enhanced structural integrity and visual appeal, ensuring long-lasting performance and durability.

Designed to connect directly to your factory exhaust connection point, this system simplifies installation without compromising performance. The mandrel-bent tubing ensures smooth bends for optimized exhaust flow, while the single 3-1/2" polished slash-cut tip adds a striking finish to your truck’s rear profile.

Manufactured with precision at Stainless Works’ state-of-the-art facility in Streetsboro, Ohio, this system reflects superior craftsmanship and American-made quality. It comes with a limited lifetime warranty on materials and workmanship for complete confidence.
