Description
Overview
The AWE Tuning 0FG Chevrolet, GMC (6.2) Exhaust System Kit is a dual 3″ T304L stainless steel cat back exhaust system engineered specifically for the Silverado ZR2 and Sierra AT4X. Built around a bespoke H-pipe and AWE’s patented drone-canceling 180 Technology®, this performance exhaust delivers an aggressive, rich muscle tone with minimal rasp — the kind of car exhaust note that turns a capable 6.2L truck into something unforgettable. AWE calls it the Best Sounding Exhaust on the Planet™ for these platforms, and every component is designed to back that claim.
Engineering & Materials
American-sourced T304L stainless steel with a .065″ wall thickness runs smoothly from front to back, connecting right after the factory emissions equipment. The 3″ tubing feeds into an H-pipe tailored specifically for the 6.2L, generating deep muscle-car character before the sound filters through the 180 Technology® resonators. Those resonators destroy drone-prone frequencies while maintaining optimal performance, so you get the volume and tone you want without the fatigue on the highway. Class-leading rigidity and precision fitment mean this exhaust system installs and sounds the way it was designed to, every time.
Tips & Finish Options
Finishing the kit are quad 4″ double-walled, slash-cut tips that exit under the rear bumper. Choose the tip finish that suits your build — chrome silver or Diamond Black — to match your truck’s aesthetic. The double-walled construction keeps the tips looking sharp against heat and the elements, adding a purposeful, aggressive stance to the rear of the vehicle.
