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 in various fashions.

Perfect tone, compliments of AWE 180 Technology®:

Keeping the aggression at the rear of the Silverado/Sierra, and out of the cabin, is AWE’s patented drone-canceling solution, 180 Technology®.

As exhaust gases exit the 5.3L 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.

By controlling the size and location of the ports and the chambers, we also control when the sound waves exit the chambers. The specific timing of when the reflected sound waves rejoin the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies.
