Korsh x COBB Tuning Engine-Back Exhaust Package — Subaru WRX Auto 2011–2014 / STI 2011–2021
Fitment: Subaru WRX (Automatic) 2011–2014 & Subaru STI 2011–2021
The complete engine-back exhaust solution for your EJ-powered Subaru. This curated package pairs Korsh's equal length headers and downpipe with the COBB Tuning cat-back exhaust system — everything from the engine to the tip, engineered to work together for maximum flow, faster spool, and a refined exhaust note. Bolt it on and feel the difference across the entire rev range.
Note: Equal length headers will remove the iconic Subaru boxer exhaust note in favour of a more conventional, refined exhaust character.
