KORSH Cat Back Exhaust

KORSH Cat Back Exhaust – Subaru WRX (GV/VA) / STI (GV/VA)

The KORSH Premium Stainless Steel Catback Exhaust System is the definitive upgrade for the Subaru WRX (2011–2021) and WRX STI (2011–2021). Engineered to extract maximum performance from both the EJ and FA series engines, this system replaces the restrictive factory exhaust with a high-flow 76mm (3.0") mandrel-bent design, delivering a perfect blend of aggressive performance and sophisticated aesthetics.

Constructed from premium 304 Stainless Steel for maximum durability and corrosion resistance, this system is finished with signature Titanium exhaust tips. These burnt-blue tips provide a distinctive motorsport styling cue while offering a high-end finish that complements the aggressive wide-body lines of the GV and VA chassis.
