CTS Turbo MK4 1.8T Downpipe High-Flow Cat

Free up your MK4 1.8T with the CTS Turbo 3" high-flow cat. The factory downpipe really chokes power once you are chipped; this one smooths exhaust flow to release it, and looks great in the process. A modular design keeps catalytic-converter installation simple, with a CNC-machined flange and smooth transitions for optimal flow.

What you get

• CNC-machined turbine discharge (downpipe) flange
• Mandrel-bent 3" stainless steel tubing
• Modular design for simple catalytic-converter installation
• Smooth transitions for optimal exhaust gas flow

Fitment

• MK4 Golf 1.8T

A CEL will appear without proper tuning software, so stage 2 software is required to avoid a check engine light.
