Evolution Racewerks Catless Downpipes, BMW X5M F95 S63 OPF

Expert's advice:

The Evolution Racewerks S63 OPF catless downpipes for the BMW X5M F95 significantly reduce exhaust backpressure, resulting in increased power and torque, faster turbo response, and a reduction in thermal load on the turbochargers. By removing both the catalytic converters and OPF filters, exhaust gas flow is optimized, allowing the engine to perform more efficiently under higher load.

Manufactured from high-quality stainless steel, these downpipes replace the OEM units and offer a precise factory-style fitment for the BMW X5M F95 with the S63 OPF engine configuration.

Please note that catless OPF-delete downpipes are not road legal in most countries and may cause issues with local emissions regulations. ECU remapping is mandatory after installation to fully optimize performance and to prevent potential check engine light warnings.
