Description

This Stainless Works Cat-back S-Tube muffler system is designed for 2011-2014 Ford F-150 V6 EcoBoost trucks. It delivers a loud, aggressive exhaust note and connects directly to the factory Y-pipe. The system features 3.5-inch diameter mandrel-bent 304 stainless steel tubing for enhanced flow, corrosion resistance, and long-lasting durability. The S-Tube straight-through muffler provides a deep, powerful tone, and a polished slash-cut tip exits behind the rear passenger tire.
