There is a reason why so many enthusiasts start modifying their truck with an aftermarket cat-back exhaust system. Our 2007 to 2013 Sierra cat-back exhaust systems are simple to install, and immediately provide numerous benefits. They just bolt into place using the stock mounting positions, so you don't need to perform major modifications to get the system in place. You and everyone else will immediately notice the differences. First off, because the cat-back includes the exhaust tip(s), it helps set a stylistic tone for the rear portion of your truck, depending on the size and finish. People will know your truck isn't exactly stock, and that you care about squeezing the most performance possible out of your Sierra. We carry a number of layout options for cat-back systems, including single rear exit, dual rear exit, single side exit, dual side exit, and even dual split side exit for an especially dramatic flair. In addition, a cat-back exhaust will add to the aggressive nature of your truck by making it louder. Just how loud the exhaust becomes depends on which cat-back you select. Each one features a muffler that's less restrictive than the stock setup, with some tuned to produce a deeper tone, while others have a unique sound. Certain systems feature larger piping as part of the cat-back, which combines with the free-flowing muffler to provide a performance boost in the form of a little more horsepower and torque. No matter which cat-back you select, know that we only carry quality systems from name brands you can trust.
