Product Description

The VRSF 4.5" Sports Cat is a high-flow downpipe upgrade for B58-powered BMW models, designed to reduce exhaust restriction, improve turbo response and unlock stronger performance when paired with the right supporting setup.

Replacing the restrictive factory catalytic converter, this sports cat uses a 4.5" cast stainless steel design with smooth, unrestricted transitions to help improve exhaust gas flow and reduce turbulence. The result is reduced backpressure, faster turbo spool and sharper throttle response.

Manufactured using mandrel-bent, TIG-welded brushed T304 stainless steel tubing, the VRSF sports cat is built for durability, precise fitment and long-term performance. The larger bore design helps support power gains, with supplied information stating 20–25hp gains with tuning.

This upgrade also delivers a louder, deeper and more aggressive exhaust note, giving the B58 engine more character while supporting Stage 1, Stage 2 and higher-performance builds.
