Downpipe, HFC, BMW F3x B58

The 034Motorsport Stainless Steel Racing Catalyst for BMW F2x/F3x B58 Vehicles is designed as a drop-in replacement for the restrictive factory catalytic converter. It offers increased horsepower and torque, reduced turbocharger lag, and improved throttle response. This upgrade eliminates the primary flow limitation in the factory exhaust system, allowing you to maximize the potential of your turbocharged engine. It features a Euro4 racing catalytic converter, integrated v-band flange, O2 sensor bung, and is constructed from 304 stainless steel. Developed in-house using 3D scanning and CAD, and tested extensively on track.
