Compatible with 1999-2007* (2007 Classic Only) Chevrolet Silverado, GMC Sierra 1500 4.8L, 5.3L engine. (*See applications below);<br><br>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 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 in. 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.
