Bomiz BMW F8x M3 M4 S55 Full Titanium Valved Catback Exhaust

Everything the S55 is capable of, in titanium.

The twin-turbo S55 in the F80 M3 and F82/F83 M4 was built to be BMW's most focused performance engine of its generation. The Bomiz Full Titanium Valved Catback takes that intent all the way through the exhaust — titanium construction for maximum weight reduction, Bomiz electronic valves for full sound control, and a system tuned to let the S55's character speak without restriction. Open the valves and you hear exactly what BMW built.

Full titanium construction, dual 3-inch piping, carbon fiber tips. Hand welded, polished, direct bolt-on. Bomiz electronic valve system 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."
