Drone-free mood control accompanied by addicting, crackling gear shifts and impressive performance. Constant, all-around satisfaction.

Touring Edition Exhaust:

The AWE Touring Edition features a 3 Non-Resonated Downpipe, and is fully armed with AWE’sproprietary drone-canceling solution,180 Technology on all sides… enabling the perfect tone, minus the drone.

The outcome? The ultimate mix of performance and sophistication. A direct bolt-on, straight-through design, the Touring Edition Exhaust delivers a civil, smooth soundtrack throughout the range while providing an enhanced in-cabin driving experience in any Drive Select mode.

Perfect sound, compliments of AWE 180 Technology.

As exhaust gases exit the B9 A4s 2.0T engine and flow into an AWE180 Technologyequipped 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 rejoin the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies.

Track Edition Exhaust:

The Track Edition Exhaust is for drivers who want to keep it cranked to 11 at all times. The Track Edition Exhaust takes the engineered design of the Touring Edition Exhaust, including the 3 Non-Resonated Downpipe, and replaces the rear AWE 180 Technology resonators with Track Edition straight pipe sections, completely uncorking the B9 A4.This version is known to get rowdy in the mid range, and may be too much for many. For that reason, this particular version cannot be returned due to sound preference. Prepare yourself.

Conversion Kits:

Its too loud! Its too quiet!

Dont worry. If youre looking to crank up a notch or bring it down, perfectly engineered upgrade paths are available. Turn your Touring Edition to a Track Edition, or vice versa, with ease. Simply unclamp the rear Touring or Track Edition sections and replace with the new configuration.

Tip Options:

All tip options include the AWE logo, and double walling to ensure a mirror finish even under hard usage. All tips are individually adjustable, allowing depth into the bumper to be set according to personal taste.
