Whether you're looking for the grabbing roar of our Track Edition or the more sophisticated tone of our Touring Edition, this family of Exhausts affords a solution for every discerning S5 owner.

S5 4.2L Track Edition Exhaust System:

The S5 Track Edition Exhaust is known for its powerful, raw V8 rumble. Still for the daily driver, this "noticeable" system lets them know you're coming.

And for S5 owners seeking an even more aggressive sound, we offer our Non-Resonated Downpipes. Our Non-Resonated Downpipes eliminate an additional set of resonators from the car, to produce a louder and deeper tone to the exhaust note.

Please note that this is a loud system and buyers should be aware. This product cannot be returned or exchanged based upon sound satisfaction.

S5 4.2L Touring Edition Exhaust System:

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®.

Perfect tone: compliments of AWE 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. More on AWE 180 Technology® in the tab above.

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.
