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. Instead of tips, this particular set up features a pair of AWE BashGuards™ -- appropriately equipped with a .125” thick reinforced stainless ring on the exhaust outlet, tucked up high out of the way of danger. 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.
