The AWE Tuning Touring Edition features a 3” Non-Resonated Downpipe, and is fully armed with AWE Tuning’s proprietary 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.






Sound Perfection: AWE Tuning 180 Technology®

As exhaust gases exit the B9 A4’s 2.0T engine and flow into an AWE Tuning 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 rejoin the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies. More on AWE Tuning 180 Technology® in the tab above.

What’s in the box?

Complete Touring Edition Exahust, two 102mm tips in desired finish, and all required installation hardware.


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 Tuning 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.

AWE Tuning B9 A4 Track Edition Exhaust





What’s in the box?

Conversion Kits

It’s too loud! It’s too quiet!

Don’t worry. If you’re 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 Tuning 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.

• 102mm slash-cut diamond black tips
• 102mm slash-cut chrome silver tips

Congratulations, very sweet music :-)

A favorite feature on my Vette is the NPP switchable exhaust.

Josh/AWE

Thanks! This suite is quite exciting simply because of all of the options and their very competitive price points. They certainly make the A4 sing!

JBrock1141

Id love to see the dyno for a tune with exhaust. Have you guys ran that combo yet?

Josh/AWE

Not yet! Should be interesting. The graphs above are what was found with A4s in 100% stock form (aside from the application of our exhaust systems).

bengtc

A little off topic but is there a soundaktor present in the B9 A4?

Josh/AWE

We didn't check, the systems sounded great with all of the factory characteristics in place.

bengtc

Cool, just picked up an A4 and this will be my first Mod! Had an AWE exhaust on my previous S4 and it sounded great!

Josh/AWE

Awesome. Congrats! What version are you leaning towards?
