Description
Description:
The Active Autowerke catless downpipe for the BMW X3M F97 and X4M F98 2020-2024 removes the single biggest restriction in the factory exhaust path, delivering maximum unrestricted flow for race and track applications.
Constructed from 304 stainless steel with mandrel-bent piping and TIG-welded construction, this downpipe is designed for maximum exhaust velocity and minimum backpressure. By eliminating the catalyst entirely, turbo spool is dramatically improved and power gains are significant. This product is intended for off-road and race track use only — it is not legal for use on public roads.
Attention:
This product is for off-road and race track use only. It is not legal for use on public roads in the United States.
