Turbo XS Uppipes are manufactured to exacting standards. By removing the restrictive factory catalytic converter uppipe, you will increase exhaust flow to the turbocharger, increase HP, reduce turbo lag, and eliminate the chances of a damaged catalytic converter destroying the turbocharger. The Turbo XS Uppipe offers a flex section to help with fitment and a stainless steel finish to improve durability. Why is the uppipe inner diameter critical? Turbo XS uses an inner diameter of 45mm, which happens to be the inner diameter of your turbochargers exhaust inlet.

This promotes the best possible performance throughout the entire RPM range by maintaining exhaust velocity. Over sizing the inner diameter of the uppipe slows exhaust velocity and creates turbulence as it enters the smaller inlet of the turbocharger, ultimately hurting turbocharger spool up. Exhaust velocity is critical!

Please note that the EGT bung shown in the picture is no longer included by TurboXS as a part of this item. This doesn't mean we can't get you an O2 or EGT bung to installed after you receive the uppipe.
