Transform throttle response, boost spool and soundtrack with this VRSF 4 inch catless front pipe for the BMW N55-powered F Series. This race-spec de-cat section pairs a high-flow 4 inch primary with a Cerakote ceramic thermal barrier to keep heat where it belongs, improving consistency and helping your turbocharger come on song sooner. It is an exceptional value performance upgrade for enthusiasts chasing Stage 2 hardware on M135i, M235i, M2, 335i and 435i models.
