AWE Tuning Touring Edition Exhaust – Chrome Silver Tip (102mm) for Subaru Impreza / WRX STI

The AWE Tuning Touring Edition Exhaust for the Subaru Impreza and WRX STI is a 3” cat-back system constructed from CNC mandrel-bent T304L stainless steel, designed to optimize exhaust flow while maintaining controlled, refined sound. It incorporates AWE’s 180 Technology® to cancel low-frequency resonance, resulting in a deeper, more defined BOXER® tone without cabin drone. The system includes an integrated front pipe and a tuned midpipe resonator to balance sound across the rev range, and the 102mm chrome silver quad tips sit neatly in the rear valance for a clean, purposeful finish. Installation uses factory mounting points, retains full emissions system compatibility, and delivers consistent fitment, performance, and tonal character under both daily driving and spirited acceleration.

Touring Edition Exhaust

• The Touring Edition Exhaust features a 3” T304L stainless steel downpipe-back design that provides straight-through flow with a deep, controlled exhaust note and no highway drone. It includes an integrated front pipe, a custom midpipe resonator, and AWE’s 180 Technology® to cancel unwanted frequencies, producing a full, rasp-free K20 tone that is responsive under boost yet quiet and composed at cruising speeds. Installation preserves factory alignment and is covered by AWE’s No CEL and Perfect Fitment guarantees. Within the 180 Technology® resonator, exhaust gases pass through precisely positioned ports into reflection chambers, where sound waves bounce and rejoin the main flow 180 degrees out of phase, eliminating low-frequency resonance while maintaining unrestricted performance.

What is 180 Technology?

• AWE’s 180 Technology® directs exhaust gases through a resonator with carefully placed ports leading into reflection chambers. The chambers are precisely tuned for each vehicle’s acoustics, allowing reflected waves to rejoin the main stream 180 degrees out of phase, canceling drone-inducing frequencies. Each resonator is engineered for the specific vehicle rather than using a generic design, ensuring consistent tone, refined sound quality, and the elimination of unwanted resonance across all 180 Technology® systems.
