Specification
Description
The Flowmaster American Thunder Cat-Back Exhaust System is designed for 2004-2008 Ford F-150 and Lincoln Mark LT trucks equipped with 4.2L, 4.6L, or 5.4L engines. This bolt-on system delivers a deep, aggressive exterior sound with a moderate interior tone, thanks to the specially designed Super 40 Series performance muffler. Constructed from 16-gauge mandrel-bent stainless steel tubing, it ensures durability and optimal exhaust flow. The dual 2.5-inch stainless steel tailpipes can be configured to exit either behind the rear wheels—ideal for towing—or straight out the back under the rear bumper for a muscular appearance. The system is finished with a pair of large 3-inch polished stainless steel tips, adding a sleek look to your vehicle. Utilizing factory hanger locations, installation is straightforward, and all necessary parts and hardware are included. This exhaust system is covered by Flowmaster's Lifetime Limited Warranty, providing peace of mind for years to come.
