Enhance the performance and exhaust character of your BMW M5 F90 or BMW M8 F91, F92, and F93 with the genuine Armytrix Stainless Steel Secondary Decatted Downpipe, engineered to reduce exhaust restrictions, improve gas flow, and deliver an even more aggressive driving experience.
Manufactured from premium T304 stainless steel, this high-flow secondary decatted downpipe replaces the restrictive factory secondary catalytic converters, allowing exhaust gases to flow more efficiently. The result is improved throttle response, reduced back pressure, enhanced turbo efficiency, and a significantly deeper, motorsport-inspired exhaust note.
Precision CNC manufacturing, TIG welding, and corrosion-resistant materials ensure outstanding durability and OEM-quality fitment. The direct bolt-on design utilizes the factory mounting points, allowing for straightforward installation without permanent modifications.
Compatible with a wide range of BMW M5 F90 and BMW M8 F91/F92/F93 models—including Competition variants—this upgrade is ideal for enthusiasts seeking maximum exhaust performance and premium aftermarket quality.
