Wake up the sound of your 2021+ Chevrolet Suburban, GMC Yukon XL 6.2L with the AWE 0FG Cat-Back Exhaust System. Built around a true-dual 3-inch configuration, the 0FG replaces the factory exhaust from directly behind the emissions equipment with a freer-flowing T304L stainless steel system designed to deliver a deeper, cleaner, more aggressive V8 tone.
AWE combines a tuned X-pipe with its patented 180 Technology® to control unwanted cabin frequencies while preserving the character you want to hear under throttle. The result is a system that adds substantial presence outside the vehicle without turning highway cruising into a constant low-frequency drone.
The entire system is handcrafted in the USA from CNC mandrel-bent, U.S.-sourced .065-inch-wall T304L stainless steel and is available with quad 4.5-inch double-walled tips in either Chrome Silver or Diamond Black. For full-size GM SUV owners who want a premium exhaust that improves sound without compromising road-trip usability, the 0FG is one of the most complete solutions available.

Why Upgrade?
The factory 6.2L exhaust does an effective job of keeping a large luxury SUV quiet, but that also suppresses much of the character of the naturally aspirated V8. The AWE 0FG is designed to bring that character back without making the vehicle unpleasant to live with every day.
That distinction matters on a Suburban, or Yukon. These vehicles regularly spend hours on the highway, carry passengers, and serve as daily drivers, so an exhaust that simply makes the truck louder can quickly become tiring. AWE's 180 Technology® specifically targets the frequencies responsible for cabin drone while allowing the exhaust to remain aggressive under acceleration.
