Compatible with the Sedan and Avant, the AWE A4 Touring Edition Exhaust rise to the occasion of unlocking performance. Our Audi A4 2.0T exhausts have earned praise from owners and the press alike, due to their unique "Jekyll and Hyde" personality. 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." Making good better: The stock A4 exhaust system has crimped tubing that obstructs exhaust flow, and robs horsepower. We fixed that. The AWE A4 Touring Edition Exhaust was designed using CAD modeling software to produce smooth gradual bends, preventing flow interference. These improvements to the exhaust path result in gains of 8-9 horsepower and 6-7 lb ft of torque at the crank. Tips:Dual 90mm (3.50 inch) slash-cut tips designed to work with the factory Sedan rear valance where both tips are on the left 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.
