This system was originally an idea that was brought to life by the BMW community. A small hole in the already super established E9x M3 Platform had an opening and we brought it to life. An affordable Valvetronic exhaust system. The exhaust brings the best of both worlds.. screaming when you want it to, or quiet enough to haul around the family.

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.”
