Product Details

This Flowmaster American Thunder Cat-back exhaust system is perfect for the person looking for deep, powerful sound outside the vehicle with a little growl inside the cab. This emissions-legal system is for 2WD & 4WD 2019-2026 GM 1500 trucks (new body style) with the 5.3L engine and factory single exhaust.

System features include full stainless steel construction, a single in/dual outlet Super 40 Series muffler and mandrel-bent dual 2.50-inch stainless steel tailpipes for maximum performance and a deep sound. Maximum dyno gains of 21 hp and 23 lb.ft. at the rear wheels. This bolt-on system utilizes the factory hanger locations and includes your choice of tailpipe exits, either dual out the rear exiting under the bumper, or dual out the side behind the rear wheels to help prevent blowing exhaust on your boat or trailer when towing. The system is finished off with a pair of large 3.50-inch double wall polished 304 stainless steel tips. Designed for a perfect fit, the system includes installation instructions and all the necessary hardware for an easy at home installation. Note: Fits 2/4 wheel drive Crew cab and double cab models.
