Stainless Works CNC mandrel-bent exhaust systems are the simply the best for improving your 2011, 2012, 2013, or 2014 Ford F-150 3.5L Ecoboost V6's performance, sound, and mileage. Made of high-grade 304 stainless steel, Stainless Works offers a wide selection of options to improve torque and horsepower, while providing the sound you want out of your vehicle. Plus, most are designed to use factory hangers. Stainless Works also constructs their mufflers entirely of stainless steel. They will never "burn in," "blow out," or change their tone—ever. Choose from turbo chambered (loud) and turbo S-tube (loudest — may be too aggressive for a daily driver).
