CTS Turbo MK4 1.8T Downpipe

Open up your MK4 1.8T with the CTS Turbo 3" stainless steel high-flow cat downpipe. The factory downpipe chokes exhaust flow and hurts horsepower, especially once you're tuned — this design lets the gases flow freely while keeping a catalytic converter in the system, with a simple modular install.

Why it works

• CNC-machined turbine discharge (downpipe) flange
• Mandrel-bent 3" stainless steel tubing with smooth transitions
• Modular design that makes catalytic converter installation simple

Fitment

• MK4 Golf 1.8T
• MK4 GTI 1.8T
• MK4 Jetta 1.8T

Proper tuning software is required to clear the CEL that will occur. Stage 2 software is required to avoid a check engine light.
