Bursting onto the scene 20 years ago with all the dynamism and power of a supercharged vehicle, Borla’s specialty in 2007-2018 exhaust systems has been honed to a sharp edge by experience and ongoing experimentation. Borla’s Sierra parts, like all their 2014-2018 cat-back exhausts, are made out of T-304 stainless steel, a high chromium content alloy that won’t develop even surface rust throughout years of use. Thanks to this material, which can resist even the corrosive gnawing of road salt in the north, all of Borla’s exhaust systems carry a 1 million mile warranty. The free-flowing design and wide-open mufflers of these 2007-2013 cat-back exhaust systems mean that your Sierra gets a boost to fuel efficiency at cruising speeds, while when accelerating or in high-torque action, the truck will get an average +7-10 horsepower and ft/lbs of torque. Buying through American Muscle also gets you free shipping on any order of $75 or higher.
