Muffler with Continuous Roving Fiberglass Technology

The Dynomax Ultra Flo Exhaust System is a premium aftermarket exhaust designed for a direct-fit, bolt-on installation on select Ford F-150 models. Constructed from T-409 stainless steel (or 16-gauge aluminized steel), the performance mufflers feature 100-percent welded construction for lifelong durability. The exclusive Continuous Roving Fiberglass technology within each muffler absorbs unwanted interior resonance, ensuring a deep performance tone without cabin drone. This system is dyno-proven to increase performance, flowing up to 2,000 SCFM and supporting up to 2,000 horsepower. The exhaust tips are constructed of T-304 stainless steel and the system comes with a limited lifetime warranty. This specific Dynomax Ultra Flo Exhaust System (39508) is designed for 2011-2015 Ford F-150 models equipped with 5'7", 6'7", or 8' beds and the 5.0 Liter V8 engine. It is a 3-inch cat-back system and is 50-state legal, producing a smooth, deep exhaust tone. Installation instructions are included, and welding may be required on some systems, though this kit is noted for its direct-fit, bolt-on nature with welded hangers, pipes, and clamps.
