Superior craftsmanship and good, sturdy materials are the hallmarks of CGS Motorsports’ 1999-2017 exhaust components for the Sierra pickup – parts designed to match up to CGS’ motto, “let it breathe.” All of CGS’ exhaust systems share certain features, like all-welded stainless steel mufflers, T-304 stainless tips, street legality in all 50 states, and a limited lifetime warranty from the manufacturer, since they’re highly resistant to rust. These components, such as their 1999-2013 cat-back exhaust systems, feature strongly flowing mandrel-bent construction, too, which shunts fumes out fast enough to generate up to +30 horsepower, +30 ft/lbs of torque, and +2 mpg fuel efficiency, depending on the vehicle and systems. All of them, including the 2014-2017 cat-back exhausts, are designed so they won’t void your truck’s GMC warranty, and install easily with bolt-on application in most cases so you can just attach them and go, free from the hassle of modifications.
