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.
NOTE: This system contains a aftermarket high-flow catalytic converted. This system is designated off-road use only. Please check with your local laws and regulations on replacing catalytic converters.
All Milltek exhaust systems are Made in England.
