Product Details

For the person who is looking for a stainless steel cat-back exhaust system with an aggressive exterior tone and moderate interior tone. The American Thunder system is heavy 16-gauge mandrel-bent stainless steel tubing for durability and maximum performance.

Includes a stainless steel Super 50 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 3.00-inch diameter 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. Notes: Fits 2/4 wheel drive standard cab/short bed models only. *Fits 2007 Classic body only. For Standard Cab/Short Bed models only.

  • Includes Hangers and Hardware for an Easy Installation
