AWE TOURING EDITION EXHAUST AND DOWNPIPE SYSTEMS FOR AUDI B8 S4

Welcome to the mother ship of 3.0T exhausts.

Our 3.0T exhaust system represents the most comprehensive exhaust development project in our company history. The 3.0T systems have paved the way for future exhaust technologies that can now be found in most every AWE Tuning ® exhaust product. We have spent considerable time and effort during development to achieve remarkable civility when idling and at part throttle cruising, while also producing a war-cry wail when full throttle is applied. These systems are handmade in-house and command respect while remaining sophisticated, refined, and powerful, all at once.

****Note: We only ship to Canada and US

Sound Perfection: AWE Tuning 180 Technology®

As exhaust gases exit the 3.0T 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 re-join the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies.

Tip options

Exhaust tips include the AWE Tuning logo and double walling to ensure a mirror finish even under hard usage. Options are as follows:

All tips are individually adjustable, so stagger and depth into bumper can be set according to personal taste.

About the downpipes

We offer our Resonated and Non-Resonated Downpipes. Our Resonated Downpipes (strongly recommended for S-tronic cars) feature resonators larger than the stock units in order to produce a mellow sound volume. Our optional Non-Resonated downpipes are suited for owners seeking a "loud" and aggressive sounding system. Both our Resonated and Non-Resonated Downpipes feature larger than stock tubing diameter.

Exhaust and Downpipe packages offer the most cost-effective solution.

Downpipe Installation Tip

Installing downpipes on these cars is arduous given the placement of the factory bolts. We had so much trouble that we made an AWE Tuning-grade tool to make it easier. If you're planning an install, our Downpipe Removal Tool is a must-have.

Upgrading to downpipes later

Not sure if you want to do the full package yet? No worries. If you purchase a Touring Edition Exhaust System alone, you have one full year from the date of the purchase to buy the complementing downpipes -- for $100 off the price of the downpipes alone. Valid for original owners only through AWE Tuning directly or through any authorized AWE Tuning dealer. Proof of purchase of the original exhaust system must be provided.

Looking for a lower-cost option? Look no further than the AWE Tuning ® Track Edition Exhaust.

For those open to a louder part-throttle experience, we're introducing the AWE Tuning ® Track Edition Exhaust. Same power and craftsmanship with less mufflers and price. Read more, here.

 

Note: In limited cases, the factory downpipes have been known to emit minor rattling noises when paired with the AWE Tuning S4 3.0T exhaust system. The possibility of rattling is eliminated with the addition of an AWE Tuning downpipe. AWE Tuning downpipes are package discounted when purchased with the exhaust, or if they are purchased within one year of an exhaust purchase.
