The 0FG is a dual 3” T304L stainless steel Cat Back configuration featuring a bespoke H-pipe and AWE’s patented drone-canceling 180 Technology®. Together, combined with precision fitment, class-leading rigidity, and signature 4” slash cut tips, you’re looking at the Best Sounding Exhaust on the Planet™ for the Silverado ZR2 and Sierra AT4X. American-sourced T304L stainless steel with a wall thickness of .065” runs smoothly from front to back, connecting right after the factory emissions equipment. An H-pipe tailored specifically for the 6.2L is met shortly after to provide an aggressive and rich muscle tone with minimal rasp before filtering through the 180 Technology® resonators to destroy drone-prone frequencies while maintaining optimal performance. Finishing things off on this kit are quad 4” double-walled, slash-cut tips, offered in chrome silver or diamond black, exiting under the rear bumper. AWE also made it easy to swap the rear portions of the 0FG to add the BashGuard (sold separately) at any time. This truly is the ultimate exhaust set up for any ZR2 or AT4X. AWE's No CEL Guarantee, Perfect Fitment Guarantee, and Lifetime Warranty come standard.
