Type-25 US Turboback Exhaust by Milltek Sport, 08+ STI, 2011+ WRX Hatch
These 100% Stainless steel exhausts are made to genuinely increase power, but without a huge increase in noise. We strongly recommend an ECU recalibration to accept the new exhaust and increase boost levels. The Milltek Sport Hi-flow Sports Cat, fully integrated into the large bore downpipes, has only 100-200 cpsi depending on application. These Cats have an open area of between 75-85% (versus 35-40% standard), thus reducing back pressure substantially and increasing flow rates.
This is the system used on the Impreza Type-25 US Edition in the Hatchback configuration.
- 2008+ Impreza WRX STI Hatchback
- 2011+ Impreza WRX Hatchback
NOTE: This system contains a high-flow catalytic converted. This system is for off-road use only and may never be used on public streets or highways. Please check with your local laws and regulations on replacing catalytic converters.
All Milltek exhaust systems and components are Made in England.
