Unlock serious flow and response with this UK‑engineered cast front pipe and 200 cell motorsport catalyst, created to integrate with a Milltek rear system.

Built for drivers who demand premium fitment and proven reliability.

We have fitted this setup for many customers and on our own builds. Feedback is consistently positive on quality, alignment and the transformation in drivability when paired with the correct software. If you are hunting for a high‑flow sports cat solution, a 3 inch performance front pipe, a 76 mm race cat upgrade or a cast turbo outlet for OPF and GPF vehicles that mates to a Milltek rear section, this is the one to choose.
