CTS Turbo MK6 Golf R 2.0T, MK2 Audi TT Quattro/TT-S 2.0T, 8P A3 Quattro/S3 2.0T High Flow CAT Downpipe

CTS Turbo is proud to release our new 2.0T AWD Downpipe with a 200 cell high flow catalytic converter.  Each CTS 2.0T AWD downpipe 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 2.0T AWD downpipe 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 powerband.  In any turbo vehicle an upgraded downpipe is a great idea, but as the Golf R, Audi TTS Quattro, 8P Audi S3 Quattro is factory equipped with the powerful K04 turbocharger it is a particularly potent power adding modification. Precision fabrication, unparalleled quality and great price point all make the CTS 2.0T AWD Downpipe with high flow catalytic converter a must-have for any VW or Audi enthusiast that values performance and their pocketbook.
