Flowmaster 17428 99-06 Chevrolet/GMC 1500 143.5 WB American Thunder Cat-Back Exhaust System

For the person who is looking for an aluminized steel cat-back exhaust system with an aggressive exterior tone and moderate interior tone. The American Thunder® system is heavy 16-gauge mandrel-bent aluminized steel tubing for durability and maximum performance. Includes a Super 40™ Series performance muffler for that perfect blend of a deep aggressive exterior sound, with a moderate interior tone that won’t drive you out of the cab when having a conversation. The dual 2.50-inch tailpipes clear the factory spare tire and give you two choices of exit locations. Straight out the back for that true dual look, or exiting out each side behind the rear wheels, which is ideal for towing. The system is finished off with a pair of highly polished 304 stainless steel tips embossed with the Flowmaster® name. Designed for an easy fit, these systems include all necessary parts, hardware and instructions for an easy installation you can do at home. Covered by our 3-year Limited Warranty. For those who prefer all stainless steel construction with a Lifetime Limited Warranty, check out exhaust system #817428. Notes: Fits 2/4 wheel drive with extended cab/short bed with 143.5-inch wheelbase.
