The American Thunder cat-back exhaust system for the 2016-2023 Toyota Tacoma Access Cab and Double Cab with 3.5L engine is perfect for the person looking for an moderately-aggressive exterior sound level while maintaining a moderate interior tone with all of the performance benefits that you would expect from Flowmaster. This flanged stainless steel system connects directly to the back of the catalytic converter and the 2.50-inch mandrel-bent tubing runs into a single inlet/dual outlet Super 50 Series muffler exiting into dual 2.50-inch mandrel-bent stainless steel tailpipes. The system uses the factory hanger locations and is finished off with a pair of 3.50-inch polished stainless steel tips exiting out the left and right side behind the rear tires, which is perfect for towing. Designed for a perfect fit, the system includes all necessary parts, hardware and detailed instructions for an easy installation you can do at home. Notes: The system fits all 2/4 wheel drives and all wheelbases.
