Flowmaster 04-08 F-150 American Thunder Cat-Back Exhaust System

This Flowmaster American Thunder® cat-back exhaust system for the 2004-2008 Ford F-150 and Lincoln Mark LT trucks with the 4.6L or 5.4L engines is perfect for the person looking for a deep aggressive exterior sound with a moderate interior tone, and with all of the performance benefits that you would expect from Flowmaster®. This bolt-on DOR/DOS (Dual Out Rear or Dual Out Side) emissions-legal exhaust system features 16-gauge mandrel-bent aluminized steel tubing flowing into a specially designed Super 40™ Series performance muffler with dual 2.50-inch aluminized steel tailpipes which use the factory hanger locations for an easy installation. The tailpipes exit either behind the rear wheels, which is ideal for towing, or straight out the back under the rear bumper for a muscular look. The system is finished off with a pair of large 3.00-inch polished stainless steel tips. The exhaust system is covered by our 3-year Limited Warranty and includes all necessary parts and hardware for an easy installation you can do at home. For those who prefer all stainless steel construction with a Lifetime Limited Warranty, check out exhaust system #817417. Note: Fits 2/4 wheel drive models all wheelbases.
