AWE Touring Edition Exhaust is 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 in every way. Seriously.
Sound Perfection: AWE 180 Technolog
As exhaust gases exit the EJ25 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. 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.
All AWE exhaust are handcrafted from 3” CNC mandrel-bent, U.S.-sourced .065” wall T304L stainless steel right here in the USA.
Choose from polished stainless steel or Diamond Black-finished exhaust tips.
Fits all 2011-2014 Subaru WRX and WRX STI sedan, and 2015-2022 WRX STI.
