AWE Tuning Audi B8 A4 Touring Edition Exhaust - Single Side Polished Silver Tips - 3015-22010
The stock exhaust system on a B8.5 A4 is full of crimped tubing obstructs
exhaust flow and robs horsepower. The AWE Tuning 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.
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, 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.
The single outlet version of our A4 performance exhaust features two 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. Each tip is
available in Chrome Silver or our recognized Diamond Black plating. The
tips sport engraved AWE Tuning 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.
