The CTS Turbo 3.5″ High-Flow CAT is designed for the front-wheel-drive (FWD) EVO4 platform and MK8 VW GTI and Audi A3 8Y vehicles with a Garrett turbocharger. The factory downpipe heavily restricts exhaust gas flow, which can negatively affect performance, particularly on vehicles with ECU tuning. This CTS Turbo downpipe allows smoother exhaust gas flow and improves the flow of the exhaust system.
It is made from 3″ mandrel-bent stainless steel tubing, with a 3.5″ cast downpipe flange and original mounting points.

- Cast stainless steel downpipe flange

- Removable reducer for installation with the original exhaust system

Important: This product is not compatible with vehicles equipped with an OPF/GPF.
Most 2022 and newer vehicles have updated “tamper-proof” downpipe mounts, which make removing the rubber mount more difficult. Installation may require using the older mount version marked 1K0253144AE.
Suitable engine tuning software is required to remove the check engine light (CEL). Check compatibility with your tuner before installation.
