AWE Resonated Performance Downpipes for B8 A4 / A5 3.2L

Resonated Downpipes versus Stock

For A5 owners looking to fine tune the sound of the Touring Exhaust even more, we suggest adding AWE Tuning Resonated Downpipes. AWE Tuning Resonated Downpipes feature larger than stock resonators in order to produce a mellow sound volume, and while they are compatible with both the Touring and Track Edition Exhaust Systems, the notable difference will be heard on the Touring system.

Sound Perfection: AWE Tuning 180 Technology™

As exhaust gases exit the 3.2L 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.
