The Racing Catless Downpipes are exclusively engineered for 2016–2024 non-US market BMW models equipped with the B48 engine (G/F Chassis). As a high-performance upgrade, this downpipe eliminates restrictive factory components to reduce backpressure, delivering 25–30hp gains (when paired with a tune), faster turbo spool, and a more aggressive exhaust note—tailored for driving enthusiasts seeking tangible performance enhancements. Crafted with precision for seamless compatibility and durability, it’s the ideal modification for international B48-powered BMWs. 

Exclusively for **non-US market BMWs**—not compatible with US-spec vehicles. Will NOT fit cars equipped with an OPF (Otto Particulate Filter). RHD (Right-Hand Drive) models require clearance adjustments or modifications to fit around the steering column. For optimal performance, pairing with a tune is recommended. All necessary installation hardware is included.
