[More Info]
This Flowmaster American Thunder® cat-back exhaust system for the 2000-2006 Toyota Tundra trucks with the 4.7L engine 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 resonator, a Super 50™ Series performance muffler and an aluminum heat shield with long stainless steel clamps. The dual 2.50-inch aluminized steel tailpipes which use the factory hanger locations for an easy installation, also include two choices for tailpipe exits, 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 and is covered by our 3-year Limited Warranty. The system includes all necessary parts and hardware for an easy installation you can do at home.
