The stock exhaust system on a B8 A5 is full of crimped tubing that impedes exhaust flow and robs horsepower. The AWE Tuning B8 A5 2.0T Touring Edition Exhaust and Downpipe Systems are designed using CAD modeling software to produce smooth gradual bends and to eliminate any interruption to the flow of exhaust gasses. Our improvements to the exhaust path result in gains of 8-9 horsepower and 6-7 lb ft of torque at the crank.
Sound Perfection: AWE Tuning 180 Technology™
As exhaust gases exit the 2.0L Turbo 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, it is possible 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.
Additional sound level tuning
For the enthusiast interested in a more aggressive sound, consider a Downpipe. The factory unit contains a fairly large straight through resonator. By replacing this large piece with a more compact but still straight through resonator, you will increase sound volume while adding a slightly deeper tone. Testing showed no power increase in adding the downpipe. It will mate to this exhaust system or any other exhaust designed to work with the stock downpipe.
Please note: This product cannot be returned or exchanged based upon sound satisfaction.
