Product Details

Description

The 034Motorsport Stainless Steel Racing Catalyst for BMW F2x/F3x B58 Vehicles is a drop-in replacement for the restrictive factory catalytic converter. The Stainless Steel Racing Catalyst offers increased horsepower and torque throughout the powerband, reduced turbocharger lag, improved throttle response, and an enhanced exhaust note. This upgrade eliminates the primary flow limitation in the factory exhaust system, allowing you to maximize the potential of your turbocharged engine.

Optimized for increased flow and maximum performance, the Stainless Steel Racing Catalyst features a Euro 3 racing catalytic converter in the factory location. This complete drop-in solution includes an integrated v-band flange at the turbine outlet, an integrated oxygen sensor bung after the catalyst, and a complete gasket/hardware kit to allow for precise fitment and ease of installation. The Stainless Steel Racing Catalyst for BMW F2x/F3x vehicles is constructed from 304 stainless steel for maximum durability, and corrosion resistance is TIG-welded and includes an integrated OE style heat isolation barrier to minimize exhaust heat transferred into the engine bay.

034Motorsport's Stainless Steel Racing Catalyst was developed entirely in-house on 034Motorsport's Development F30 BMW 340i, utilizing the latest in 3D Scanning Technology, CAD Software, and Rapid Prototyping Techniques. Final production units were tested extensively on track in B58 vehicles before release.
