Bomiz BMW F90 M5 S63 Downpipes

The S63 downpipes are where the F90 M5's power story starts.

BMW's F90 M5 runs one of the most capable twin-turbo V8s in any performance sedan — and the OEM downpipes are the first restriction in the path. The Bomiz F90 M5 Downpipes open that path from the turbo outlets out, improving flow and sharpening the exhaust note that carries through the rest of the system. T304 stainless steel, hand welded, direct bolt-on. The S63 does the rest.

WARNING: Please note that certain aftermarket exhaust systems may not comply with applicable US (including California) laws and regulations, and may therefore be prohibited for use on highways or roads, or on roads or vehicles otherwise subject to emissions control requirements. California prohibits the use of any aftermarket exhaust system that modifies, removes or replaces original equipment catalysts, unless CARB has issued an Executive Order as to such part or system.

BOMIZ parts or exhaust systems/components used or intended for use on "racing vehicles" (i.e. a competition vehicle used exclusively for competition on closed-course circuits) do not require an exemption or Executive Order from CARB to be sold in California. However, such parts are prohibited from use on California public highways or roads, even if occasionally used "off-road."
