VRSF BMW F8X S55 Catless Downpipes

With a unique cast stainless steel V-band to pipe transition, these 3in downpipes are the best value catless downpipes available on the market for the S55, with genuine gains of 20-25hp and 25-30tq when tuned. By eliminating the restrictive catalytic converters in the factory downpipes, backpressure is significantly reduced, resulting in faster turbo spool, a genuine increase in power, and a more aggressive exhaust note.

Rather than necking down closer to the turbos the way most competitor downpipes do, these feature a full 3in design right up to the last couple of inches of pipe, allowing a genuine increase in flow. A CAD/CAM-designed cast flange provides a seamless flange-to-pipe transition, hand-made from mandrel-bent, TIG-welded 3in 304-grade stainless steel with smooth radius bends to decrease turbulence. Grade 12 installation hardware is included with purchase. Optional ceramic coating is available using Cerakote's high-temperature ceramic coating, rated to withstand temperatures up to 1800°F (980°C).

Works with: Both RHD and LHD models, no modification necessary.

Intended use: removal of emissions equipment means this part is intended for closed-course/competition use, not for road use where emissions compliance is required.
