08-12 Audi B8 S5 4.2L Touring Edition Exhaust System – Diamond Black Tips

Touring Edition Exhaust:

The more civilized member of the family is the S5 4.2L Touring Edition Exhaust. In addition to the central muffler from the Track Exhaust, our Touring Edition system features an x-pipe for enhanced exhaust scavenging and also features AWE 180 Technology.

AWE’s Pantented 180 Technology:

As exhaust gases exit the 4.2L 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 re-join the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies.

For S5 owners looking to fine tune the sound even more, we offer our Resonated Downpipes. Our Resonated Downpipes feature resonators larger than the stock units, along with larger diameter tubing in order to produce a mellow sound volume.

Made in PA, USA:

Engineered, designed, and manufactured in-house at AWE using US-sourced .065-wall T304L stainless steel to achieve a tone deeper than everyone else.
