AWE Tuning Product Description
The best just got better.
Signature AWE howl, delivered. The Touring Edition is the sophisticated member of the B9 S4 exhaust family.
The Touring Edition Exhaust removes the factory valving and replaces it with AWE's 180 Technology drone-cancelling resonators (and electronic valve simulators). This solution provides for a perfect, signature AWE experience: civil within the cabin while cruising, yet all the pops and burbles during acceleration and downshifts.
The Touring Edition Exhaust comes complete with 180 Technologyå¨ resonators, a precision-engineered x-pipe, resonated downpipes, and your choice of 90 or 102mm tips in either diamond black or chrome silver.
Sound Perfection: AWE 180 Technologyå¨ Perfect tone, compliments of AWE 180 Technology.
As exhaust gases exit the 3.0T engine and flow into an AWE 180 Technologyå¨ 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 rejoin the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies. Cool, right? Learn more on AWE‰۪s 180 Technologyå¨ in the tab above.
