Product Description
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 stainless steel 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.

Straight out the back for that true dual look, or exiting out each side behind the rear wheels, which is ideal for towing.
