Frequently asked questions
Does this Downpipe also fit the M140i with OPF?
No, this version is only suitable for pre-OPF models (up to 2018). A different variant is required for OPF models.

What is the difference between the decat and sportcat versions?
The decat offers maximum flow and sound, whilst the sportcat maintains slightly more back pressure and is slightly quieter.
