CTS Turbo is proud to release our downpipe with a 200 cell high flow catalytic converter for MK1  VW Tiguan/8U Q3 1.8T/2.0T.  Each CTS MK1 Tiguan/8U Q3 high-flow cat is 100% tig welded, constructed using 3" T304 Seamless Stainless Steel, and includes installation hardware and stainless steel clamps.  Lesser products can be had without stainless steel construction, or with seamed stainless steel, which can crack and decay over time.  The CTS Turbo Tiguan high-flow cat eliminates the factory downpipe, increases turbo spool up, and peak power.  The increased piping diameter of 3" allows for exhaust gases to exit the turbo and wastegate with less turbulence which all result in more power and torque throughout the entire power-band.  In any turbo vehicle, an upgraded downpipe is a great idea, and this is a particularly potent power adding modification. \n \nPrecision fabrication, unparalleled quality and great price point all make the CTS MK1 Tiguan 1.8T/2.0T high-flow cat a must-have for any VW enthusiast that values performance and their pocketbook. \n \nProduct Details: \n
