Flowmaster's® Signature Series Cat-back exhaust system fits the 2015-2020 Ford F-150 with 2.7L, 3.5L EcoBoost, 3.5L Ti-VCT, and 5.0L engines. This brushed 304 stainless steel performance exhaust system bolts up to the factory flange with a large 3.00-inch mandrel-bent tube flowing into the TIG welded 304 stainless steel Signature Series "straight-through" performance muffler. This premium exhaust system is TIG welded for a stronger, more precise weld that looks as good as this system sounds. The large single mandrel-bent tailpipe exits behind the passenger side rear tire and is finished off with a large 4.50-inch PVD coated black chrome exhaust tip embossed with the Flowmaster name. This system creates a deep powerful sound outside the vehicle with a moderate tone inside the cab and utilizes the factory hanger locations for an easy installation. Max dyno gains of 20 hp and 22 lb-ft at the rear wheels. Includes all necessary parts, hardware and easy to follow detailed instructions.

Features:

  • • Brushed 304 stainless steel offers maximum corrosion resistance for a cleaner and more high-end appearance.
  • • TIG welding offers a more precise weld, better heat control and high-end appearance compared to MIG welding.
  • • Black chrome tips offer a stylish upscale look.
  • • Signature Series muffler offers an aggressive to moderate performance tone and increased performance over the stock system.
  • • Installer friendly design allows for an at home installation.
  • • Dyno proven performance gains you can feel.
  • • Increased power and torque over the stock exhaust system.
  • • Brushed appearance removes tooling marks for a cleaner overall look.
