Our most frequently asked questions

• Is ECU tuning required? Yes. A suitable ECU map (Stage 2) is essential to make use of the gain and to avoid a check engine light related to the lambda sensors. This is the question buyers ask most, and the answer is always the same.
• What about the roadworthiness inspection? A decat downpipe will not pass the emissions inspection. This product is intended for motorsport use only.
• Exhaust compatibility: this downpipe is designed to connect to a Milltek exhaust system. Check the correct version if you keep the original exhaust.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubing to preserve the internal diameter and a fit developed on the vehicle. The result: a clean installation without modification, and a sound tuned to remain pleasant for everyday driving.
