$1149.95

Looking to give your 2007-2013 GM Silverado or Sierra 1500 with a 5.3L engine a boost in sound? Our American Thunder Catback exhaust system is just what you need! This system strikes the perfect balance, delivering a moderately aggressive sound both inside and outside your truck.

Crafted with 3.00-inch mandrel-bent stainless steel tubing, it flows seamlessly into a Super 40 Series muffler, producing a deep, powerful tone that you'll love. Plus, the 2.50-inch stainless steel tailpipes can be configured to your liking—choose to have them exit straight out the back under the bumper for that muscular look, or go for the stylish exit behind the rear tires on each side. The latter is especially handy when you're towing a boat or RV.

To top it all off, the tailpipes feature large 3.50-inch double wall polished stainless steel tips, ensuring your truck looks as good as it sounds. Our system comes with all the necessary parts and hardware for a straightforward installation, and it’s backed by our Lifetime Limited Warranty.
