Our Resonated Downpipes feature larger-than-stock tubing diameter as well as resonators larger than the stock units in order to produce a mellow sound volume.
Downpipe installation tip:
Installing downpipes on these cars is arduous given the placement of the factory bolts. We had so much trouble that we made an AWE Tuning-grade tool to make it easier. If you’re planning an install, our is a must have.
Sound. Perfected. AWE Tuning 180 Technology™:
180 Technology™ is AWE Tuning’s proprietary sound cancellation technology. It’s why you’ll love this system.
As exhaust gases exit the 3.0T engine and flow into an AWE Tuning 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 re-join the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies.
