Bomiz BMW E9x M3 S65 Valvetronic Axle-Back Exhaust

The valved axle-back the E9X M3 community always wanted. The Bomiz E9X M3 Valvetronic Axle-Back was born from a gap in one of BMW's most established enthusiast platforms. The E9X M3 community wanted an exhaust that could deliver the best of both worlds — something that could scream when the valves are open, yet stay quiet and civilized when life calls for it. We brought that idea to life with a system built for enthusiasts who wanted real sound control without losing the emotion that makes the S65 so special. Built from SS304 stainless steel and equipped with Bomiz Valve Technology, this system gives the E9X M3 a more alive, more engaging character while keeping everyday drivability intact. Open it up and the car takes on a more aggressive, high-revving personality. Close it down and it becomes refined enough for normal driving, long trips, or hauling the family around. To us, this is more than an axle-back — it is the community's idea, turned into a product with purpose. Hear it — valves open vs. closed This is exactly what your S65 will sound like. Turn your sound on.

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."
