Maximise the potential of your B58-powered BMW with the VRSF 4.5” Motorsport Downpipe. Designed for serious performance 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 downpipes 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: These race downpipes are intended for off-road and track use only. Installation will trigger a check engine light (CEL) unless paired with appropriate ECU software or a lambda sensor spacer.

Compatibility:

  • BMW F20 M140i

  • BMW F22 M240i

  • BMW F30 340i and F32 440i

Who Is This Product For?

Ideal for enthusiasts seeking to significantly improve exhaust flow, turbo spool and overall engine performance. This sports cat is especially suited to vehicles running Stage 1 or 2 remaps, hybrid turbo conversions or those regularly driven hard on track or fast road.

If you’re chasing a deeper, more aggressive exhaust note while unlocking the full potential of your B58, this VRSF Sports is a must-have.

Great read, interesting, engaging, outstanding!
Format: Hardcover
Holland and Murray nailed it ! Outstanding work. I follow them on you tube and they bring you back in time with enthusiasm and knowledge. They genuinely love the subject matter and present it in a way that is not boring or too technical. In this book they call it as they see it and make you want to read more!

Now what?
Format: Hardcover
I am a student (not scholar) of WW II history mostly because of the many men and women in my family who served in this war. Holland and Murray bring a new experience to WW II reporting. We know that surrenders happened, and when and where. But this book gives the reader the "then what happened" ? and named individuals and told of their experiences while they struggled to figure out "what next?". They are lucky to be alive but confused as if they were experiencing an altogether new "battle" asking What shall we do? where shall we go, where will we be safe, how do we live now? This is a fascinating view of the joy and the terror and the miracle of having survived.
