Maximise the potential of your B58-powered BMW with the VRSF 4.5” Sports cat. Designed for serious performance, tuning and motorsport enthusiasts, these high-flow downpipes replace the restrictive factory catalytic converters with a precision-engineered, mandrel-bent and cast stainless steel system to dramatically improve exhaust flow, turbo response, and overall power delivery.

Unlike typical fabricated designs, VRSF’s cast stainless steel sports cats feature smooth, unrestricted transitions and a durable brushed finish for both performance and aesthetics. The larger 4.5” bore reduces backpressure, allowing the B58’s turbochargers to spool faster and deliver noticeable gains in horsepower, torque and throttle response — particularly when combined with an ECU remap.

The result is a sharper, more responsive driving experience, coupled with a louder, deeper exhaust tone that brings the B58 engine character to life.

Key Features:

  • Full 4.5” cast stainless steel design for optimal flow and durability

  • Smooth, gradual transitions for improved exhaust gas velocity and reduced turbulence

  • Mandrel-bent, TIG-welded brushed T304 stainless steel tubing

  • Significant reduction in backpressure, improving turbo spool and throttle response

  • Substantial gains - 20-25 HP with tune

  • Enhanced, aggressive exhaust note with increased volume and character

  • Direct fit bolt-on replacement for the factory downpipes 

  • Includes all necessary gaskets and mounting hardware

  • Lifetime warranty against manufacturing defects

Note: OPF/GPF CARS WILL REQUIRE REMOVAL OF OPF/GPF PRESSURE SENSOR AND MAPPING OUT
The use of de-cats, sports cats are for off road/motorsport use only. Using these parts may inhibit your vehicle from passing a MOT test.

Compatibility:

  • BMW F20 M140i

  • BMW F22 M240i

  • BMW F30 340i and F32 440i

Does Not Fit Polaris Ranger
Not compatible for Polaris Ranger as it was advertised. Not the correct thread so it will strip. Do not buy if you need it for a Polaris UTV.

Found one that fit.
It's a shame you have to buy an assortment just to find one that would work for my vehicle. You can't find an OEM one without buying the whole headlight assembly. Oh well.....
