MIA's Description

Upgrade your 2008-2014 Subaru WRX STI Hatchback with the HKS Super Turbo Catback Exhaust, designed for a balance of power and refined sound. It reduces exhaust pressure, maintains comfortable interior noise, and features 124mm burnt titanium tips. The piping diameter is 75mm to 60mm, with a sound output of 90db. It bolts directly onto the factory downpipe (an OEM downpipe to 3-inch adapter may be required).
