Bomiz BMW F8x M3 M4 S55 Valved Catback Exhaust

The S55 in the F8x M3 and M4 sounds like nothing else in the BMW lineup. This is the system built around that.

BMW's twin-turbo S55 was the engine that took the M3 and M4 in a different direction from the S65 that came before it. The character is different — more forced, more aggressive, a different kind of fury. The Bomiz valved catback with X pipe and H pipe combination was built to get every dimension of that S55 character out in the open. The valve system gives you full control: quiet when the situation calls for it, fully unleashed when it doesn't.

Stainless steel 304 construction, dual 3-inch piping, carbon fiber tips. Hand welded, polished, bolt-on. Bomiz electronic valve control with wiring and controller included.

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."
