AWE Tuning Touring Edition Exhaust for VA STI / GV WRX / GV STI Sedan - Chrome Silver Quad Tips (102mm) (3015-42104)

BOXER uncorked: A direct bolt-on, full 3" straight-through design. The Touring Edition allows the WRX / STI to deliver its famous rumble without rasp or in-cabin drone, while introducing intoxicating crackles when shifting, thanks to AWE's proprietary drone-canceling solution, 180 Technology. This configuration compliments the EJ25 is every way. Seriously. Conversion Kits: AWE made it easy to convert from a Track Edition to a Touring Edition, or vice versa, if you decide at a later date to turn it up, or turn it down

AWE's patented 180 Technology works a little something like this: As exhaust gases exit the engine and flow into an AWE 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. Depending on the sound requirements of each vehicle, AWE acoustic engineers adjust the size and location of the ports and the chambers. By controlling the size and location of these key elements, 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. AWE 180 Technology is not on a one size fits all" concept. Rather, AWE engineers design sound cancelation resonators based upon the specific acoustics generated by vehicle types, thereby ensuring perfect sound, every time. It's one of the reasons AWE exhausts have earned a reputation for the perfect tone, regardless of application. The result? The removal of unwanted tones in all AWE 180 Technology-equipped exhaust systems. The sound produced by this formula is the perfect, signature note. Unlocked performance and spot-on tone, every time.
