Description
Overview
The AWE Tuning 0FG Exhaust System Kit is a dual 3″ T304L stainless steel Cat Back configuration engineered specifically for the Chevrolet Silverado ZR2 and GMC Sierra AT4X running the 6.2L V8. 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 — what AWE calls the Best Sounding Exhaust on the Planetâ„¢ for these trucks. If you’ve been comparing a Borla exhaust, a Corsa exhaust, or a MagnaFlow exhaust for your 6.2, this is a true catback exhaust built to a class-leading standard.
How It Works
American-sourced T304L stainless steel with a substantial .065″ wall thickness runs smoothly from front to back, connecting right after the factory emissions equipment to preserve the truck’s legal status. Just downstream, an H-pipe tailored specifically to the 6.2L generates that deep, throaty muscle-car character. From there, the exhaust flow filters through the 180 Technology® resonators, which destroy drone-prone frequencies while maintaining optimal performance — so you get the sound you want at wide-open throttle without the cabin boom on the highway.
Tips & Finish
Instead of traditional tips, this setup features a pair of AWE BashGuardsâ„¢, equipped with a .125″ thick reinforced stainless ring on the exhaust outlet and tucked up high, out of the way of trail damage. It’s a purpose-built detail for the off-road-focused ZR2 and AT4X, blending the durability of a rugged truck exhaust system with AWE’s precision fitment and rigidity.
