VRSF BMW S63TU M5/M6 (F10/F12) Catless Downpipes

These 3in downpipes are the best bang-for-buck modification available for the S63, with genuine gains of 50hp and 60tq 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 greater increase in flow. They feature a CNC stainless steel V-band to pipe transition for a precise, factory-quality connection, hand-crafted from SS304 stainless steel, with Grade 12 installation hardware included as standard. Optional ceramic coating is available using Cerakote's high-temperature ceramic coating, rated to withstand temperatures up to 1800°F.

Works with: Both left-hand drive and right-hand drive models.
