VRSF B58 Catless Racing Downpipe BMW M340i M440i G20 G22 G26

Unrestricted flow. Faster spool. More aggressive sound. Built for the B58.

Take your BMW B58 to the next level with the VRSF B58 Catless Racing Downpipe, engineered to dramatically reduce exhaust restriction and improve exhaust flow between the turbocharger and the mid pipe.

Featuring a large 4.5 inch diameter design, hand crafted from 304 stainless steel, this downpipe provides a smooth and efficient exhaust path while maintaining excellent durability under high heat and demanding driving conditions.

The catless configuration removes the restrictive factory catalytic converter, helping reduce back pressure and allowing the turbocharger to spool more efficiently. When combined with an appropriate performance tune, the result can be improved power, sharper throttle response, faster turbo spool, and a significantly more aggressive exhaust note. VRSF states potential gains of approximately 25 to 30 horsepower with tuning.

Precision Construction

The VRSF B58 downpipe is built from TIG welded 304 stainless steel with a CNC machined 304 stainless steel flange. Smooth radius bends are used to reduce turbulence and promote efficient exhaust flow, while the brushed finish gives the system a clean motorsport inspired appearance.

Tuning & Important Information

This Track Limited Racing Downpipe is a catless configuration and is intended for track, competition, and off-road applications. Removing the factory catalytic converter may not comply with emissions or road-use regulations in your jurisdiction.

A suitable ECU calibration is recommended when upgrading to a catless downpipe. Additional tuning may be required to properly account for the increased exhaust flow and prevent warning lights.

Not intended for use on emissions-controlled public roads where prohibited by law.
