Introducing the new FlowFX® Cat-back exhaust system for the 2015-2020 Ford F-150 with 2.7L, 3.5L Ecoboost, 3.5L Ti-VCT and 5.0L engines. This stainless steel performance exhaust system bolts up to the factory flange with a large 3.00-inch mandrel-bent tube flowing into the "straight-through" FlowFX performance muffler.

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. Includes all necessary parts, hardware and easy to follow detailed instructions.
