SS304 High-Flow 200 Cell Catted Downpipes for BMW N63 4.4L Twin-Turbo V8 Without OPF
Designed for compatible BMW M550i G30, M850i G14 / G15 / G16 and X5 G05 models powered by the N63 4.4L twin-turbo V8 without OPF / GPF, these high-flow 200 cell catted downpipes replace the restrictive factory catalytic converter sections with a significantly freer-flowing exhaust path.
Manufactured from high-quality SS304 stainless steel, the downpipes are engineered to withstand the extreme temperatures generated directly after the twin turbochargers while providing excellent corrosion resistance, strength and long-term durability.
The integrated 200 cell high-flow catalytic converters provide substantially less exhaust restriction than the factory catalyst sections while retaining a catted exhaust configuration. Reduced backpressure helps improve exhaust gas flow and allows the N63 4.4L twin-turbo V8 to breathe more efficiently.
The freer-flowing configuration also increases turbocharger sound and produces a deeper and more aggressive V8 exhaust tone while maintaining a more refined setup compared with fully catless downpipes.
Vehicle-specific routing, flange geometry and mounting points are designed around the factory BMW N63 exhaust system. Original oxygen sensors and applicable OEM components should be transferred during installation where required. Professional installation is strongly recommended.
