The muffler of any exhaust system has the biggest effect on the exhaust note you hear, and the 2007-2017 GMC Sierra mufflers offered by AmericanTrucks are chosen to make everyone within hearing sit up and take notice. A deep, growling, commanding note is what you can expect from most of these mufflers, which are also tuned so that your cab will remain free of droning and high-pitched noises. Generally made out of high quality stainless steel with extra-strong, welded seams that won’t leak even under the pressure of a boosted air and exhaust system, these mufflers are designed to work over the long haul and often come with a limited lifetime warranty. They’re also high flow designs, with offset/offset, offset/center, and center/center piping choices, which will fit in with an aftermarket cat-back to produce greatly improved scavenging from the cylinders – putting even more pep in your Sierra.
