Frequently Asked Questions

• Do I need an ECU remap? Yes. A suitable Stage 2 map is essential to get the full gain and avoid a check engine light caused by the lambda sensors. This is the most frequently asked question from buyers, and the answer is always the same.
• What about the technical inspection? A decat downpipe will not pass the emissions test. This product is intended for motorsport use only.
• Exhaust Compatibility: this downpipe is designed to connect to a Milltek exhaust. Check the correct version if you keep the OEM exhaust.

Why Choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent tubes to preserve the internal diameter and a fit developed on the vehicle. Result: a clean fitting, no modification needed, and a tone tuned to stay pleasant for daily use.
