Product details
OVERVIEW
Evolution Racewerks Competition Series catless downpipes free up significant exhaust flow on the S55 twin-turbo engine in the F80 M3, F82/F83 M4 and F87 M2 Competition. The catless design delivers maximum flow for race applications, with faster spool and more top-end power than the restrictive factory downpipes.
