Ford F-150 Performance Exhaust - Flowmaster American Thunder Cat-Back (2004-2008). This bolt-on, emissions-legal system delivers a deep, aggressive exterior note with a moderate interior tone.

Designed for 2004-2008 Ford F-150 and Lincoln Mark LT trucks with 4.6L or 5.4L engines (2/4WD, all wheelbases), this kit uses 16-gauge mandrel-bent aluminized steel tubing feeding a Super 40™ Series performance muffler. Dual 2.50-inch tailpipes exit either behind the rear wheels (ideal for towing) or straight out the back, and it finishes with a pair of 3.00-inch polished stainless tips. It reuses factory hanger locations, is dyno-tuned for performance, and includes all required parts and hardware. Backed by Flowmaster’s 3-year Limited Warranty.
