Emissions rules vary by state and some inspections only accept original-type catalysts, so check with your state roads authority before road use. May affect your new-car warranty; declare it to your insurer.

The details

Built for the build

Twin stainless downpipes with high-flow 200-cell catalysts for the S58, which the G80/G82 M3/M4 and G87 M2 share. They improve spool and reduce exhaust temperatures on tuned cars, and they need a matching calibration.
