Evolution Racewerks Catted Downpipes, BMW X5M F95 S63

Expert's advice:

The Evolution Racewerks catted downpipes for the BMW X5M F95 S63 are designed to significantly improve exhaust flow by reducing backpressure directly after the turbochargers. This results in increased power and torque, sharper throttle response and quicker turbo spool throughout the entire rev range.

Constructed from high-quality stainless steel with mandrel-bent piping, these downpipes ensure optimal flow and a precise OEM-style fit. The integrated flex sections help absorb heat expansion and engine movement, contributing to long-term durability and reliability under high load.

Equipped with high-flow 200-cell sport catalytic converters, these downpipes offer an excellent balance between performance and usability for tuned applications. ECU recalibration is required after installation to fully optimize performance and to prevent fault codes.

Please note that emissions regulations may vary by region and can affect road legality.
