Unlock sharper response, stronger mid-range pull and a richer exhaust tone with this British-built performance front pipe featuring the premium HJS 200 cell motorsport catalyst. Designed to mate to a Milltek rear section on OPF and GPF equipped MQB 2.0 TSI models, this big-bore turbo outlet prioritises flow and fit without compromise.

We have installed this setup many times at MJ Modifications and it has been faultless. Fitment is precise, spool is noticeably quicker and customers consistently praise the quality and driving feel when paired with the correct software calibration.
