AWE A4 Research and Development has yielded an exhaust that is remarkably civil while idling / part throttle cruising, but unleashed at full throttle it produces what some have called a "war-cry wail." Sophisticated, refined, and powerful, all in one package. Making good, better The stock exhaust system on a B8.5 A4 is full of crimped tubing obstructs exhaust flow and robs horsepower. The AWE B8.5 A4 Touring Edition Exhaust and Downpipe 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. AWE A4 Touring Edition Exhaust - Quad Outlet (Four total tips, two on each side) The quad-tip version of our A4 Touring Edition Exhaust features four 90mm (3.50 inch) slash-cut tips, located on each side of the car. The tips sport engraved AWE logos and are double-walled to ensure a mirror polish, even under hard usage. Each tip is individually adjustable, so stagger and depth into bumper can be set according to personal taste. This system will not work with the factory valance and requires a quad-tip conversion. The purchase of an Conversion Kit in order to allow quad tip fitment. Additional sound level tuning For the enthusiast interested in a more aggressive sound, we offer our Resonated Performance 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, we were able to increase sound volume while adding a slightly deeper tone. Testing showed no power increase in adding the downpipe. It will mate to our 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.
