Take your BMW M5 F90 or BMW M8 F91/F92/F93 to the next level with the genuine Armytrix Ceramic Coated Secondary De-Catted Downpipes, engineered to maximize exhaust flow, reduce exhaust temperatures, and deliver a deeper, more aggressive exhaust note. Designed specifically for BMW's powerful 4.4L S63 twin-turbo V8, these secondary de-cat downpipes eliminate restrictive secondary catalytic converters for improved performance and enhanced driving excitement.
Constructed from premium T304 stainless steel and finished with a durable high-temperature ceramic coating, these downpipes provide exceptional thermal insulation while improving exhaust gas velocity. The ceramic coating helps reduce radiant engine bay heat, protects surrounding components, and enhances long-term durability under demanding driving conditions.
Precision-engineered for OEM-quality fitment, the Armytrix secondary downpipes install directly onto compatible BMW models without modification and integrate seamlessly with both factory and Armytrix exhaust systems.
Compatible with selected BMW models, including:
- BMW M5 F90 Sedan (600 hp)
