AWE Tuning Track Edition Exhaust – Non-Resonated Diamond Black Tips (102mm) for B9 Audi S4

The AWE Tuning Track Edition Exhaust for the B9 Audi S4 uses a straight-through, non-resonated cat-back design with larger-diameter tubing to reduce restriction and increase exhaust flow from the 3.0T V6. Without resonators or drone-canceling features, it produces a consistently louder, sharper exhaust note with more pronounced turbo and overrun sounds, making the engine’s character more apparent at all speeds. This setup is better suited for drivers who are comfortable with higher cabin volume in exchange for a more direct and unfiltered sound profile. The 102mm diamond black tips add a darker, understated finish at the rear, and the system is designed around factory mounting points to maintain proper alignment and straightforward installation.

Track Edition Exhaust

• For those who like it raw and rowdy, the Track Edition is for you. The Track Edition shares the same integrated frontpipe, bespoke midpipe resonator, and precision engineering as its Touring Edition counterpart, minus AWE’s patented drone-canceling solution, 180 Technology®.
• In place of the 180 Technology® resonator in the rear lies a Track Edition straight section. As a result, this version is known to get (really) rowdy in mid-range acceleration and deceleration, and may be too much for many. You’ve been warned.

What is 180 Technology?

• AWE Tuning’s patented 180 Technology works as follows: As exhaust gases exit the engine and flow into a resonator equipped with AWE’s 180 Technology, they pass through strategically located ports and into reflection chambers. Sound waves carried by these exhaust gases bounce off the walls of the reflection chambers. Depending on the sound requirements of each vehicle, AWE’s acoustic engineers adjust the size and location of the ports and chambers. By controlling these key elements, AWE Tuning can manage when the sound waves exit the chambers. The precise timing of when the reflected sound waves rejoin 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’s 180 Technology is not based on a “one size fits all” concept. Instead, AWE engineers design sound-canceling resonators based on the specific acoustics generated by different vehicle types, ensuring perfect sound every time. This approach is one reason AWE exhausts have earned a reputation for delivering the perfect tone, regardless of the application.
• What It Means to You:
  • The result? The elimination of unwanted tones in all AWE 180 Technology-equipped exhaust systems. The sound produced by this technology is the perfect, signature note, providing unlocked performance and spot-on tone every time.

Exhaust Tips

• Each exhaust system is equipped with three 4.5” double-walled, slash-cut tips, available in chrome silver or diamond black, each featuring a stamped AWE logo. The tips are individually adjustable, allowing for customization of their depth into the bumper based on personal preference.

Nope, It’s Not Valved

• During research and development, AWE conducted an extensive evaluation of the factory valve’s behavior under various driving conditions. They determined that there is no significant change in volume between modes requiring a valve. The valve remains closed only in comfort mode, opening upon reaching a throttle threshold. In Sport and Sport+ modes, the valve stays open, with Sport+ introducing burbles from the ECU. In the stock configuration, the exhaust routes through the side mufflers when the valve is closed to reduce interior volume and drone-prone frequencies, and through the center when the valve is open.

Conversion Kits

• AWE has made it simple to convert between Track and Touring Editions if a change in interior volume is desired later.
