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.
Hand-crafted, every detail of these exhausts was labored over to ensure maximum performance and longevity:
+ 18hp, +12tq at the crank
Available with Chrome Silver or Diamond Black adjustable tips
Increased pipe diameter to 2.5" to better let the engine exhale
Engineered, developed, tested and manufactured in-house
Stainless steel center muffler with composite acoustical and stainless steel packing materials
Strategic elimination of mufflers to release tone
Thick .065" wall T-304 stainless steel tubing
High quality stainless steel band clamps
Lifetime Exhaust Warranty
Tips:
Both versions of our S5 4.2L Exhaust System come with 90mm (3.5 inch) Slash Cut Tips, available in standard Chrome Silver or our noted Diamond Black finishes. The tips sport engraved AWE logos and are double walled to ensure a mirror polish, even under hard usage. Each tip is individually adjustable, so stagger and depth into bumper can be set according to personal taste.

What is 180 Technology®?
AWE's patented 180 Technology® works a little something like this: As exhaust gases exit the 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. Depending on the sound requirements of each vehicle, AWE acoustic engineers adjust the size and location of the ports and the chambers. By controlling the size and location of these key elements, 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.
Consistency through change.
AWE 180 Technology® is not on a “one size fits all” concept. Rather, AWE engineers design sound cancelation resonators based upon the specific acoustics generated by vehicle types, thereby ensuring perfect sound, every time. It’s one of the reasons AWE exhausts have earned a reputation for the perfect tone, regardless of application.
What it means to you.
The result? The removal of unwanted tones in all AWE 180 Technology®-equipped exhaust systems. The sound produced by this formula is the perfect, signature note. Unlocked performance and spot-on tone, every time.
