The 0FG is a 3" T304L stainless steel Cat Back configuration featuring AWE's patented drone-canceling 180 Technology. Together, combined with precision fitment, class-leading rigidity, and tailored tip options for all bumper variations, you're looking at the Best Sounding Exhaust on the Planet for the 5.3L-equipped Silverado/Sierra. American-sourced T304L stainless steel with a wall thickness of .065" runs smoothly from front to back, connecting right after the factory emissions equipment. After exiting the 180 Technology resonator, the 0FG exhaust brings up the rear with dual Chrome Silver tips in split rear fashion. The last exhaust you'll ever need for your Silverado.

AWE's patented 180 Technology works a little something like this: As exhaust gases exit the engine and flow into an AWE 180 Technology-equipped resonator, they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. Depending on the sound requirements of each vehicle, AWE acoustic engineers adjust the size and location of the ports and the chambers. By controlling the size and location of these key elements, we also control when the sound waves exit the chambers. The specific timing of when the reflected sound waves re-join the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies. AWE 180 Technology is not on a one size fits all" concept. Rather, AWE engineers design sound cancelation resonators based upon the specific acoustics generated by vehicle types, thereby ensuring perfect sound, every time. It's one of the reasons AWE exhausts have earned a reputation for the perfect tone, regardless of application. The result? The removal of unwanted tones in all AWE 180 Technology-equipped exhaust systems. The sound produced by this formula is the perfect, signature note. Unlocked performance and spot-on tone, every time.
