Milltek Sport decat turbo downpipe for BMW 2 Series G87 M2 / 3 Series G80-G81 M3 / 4 Series G82 M4

Our most frequently asked questions

• Do I need a remap? Yes. A suitable Stage 2 map is essential to make the most of the gain and to avoid a warning light linked to the lambda sensors. It is the most frequently asked question from buyers, and the answer is always the same.
• What about the roadworthiness inspection? A decat downpipe will not pass the emissions test. This product is reserved for motorsport use.

Why choose Milltek Sport?

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