Bomiz BMW F3x 335i 435i N55 Valved Catback Exhaust

The N55 inline six doesn't get the credit it deserves. Properly exhausted, that changes.

BMW's N55 B-series is one of the most capable turbocharged inline sixes in production — smooth, strong, and with a character that the factory exhaust keeps politely contained. The Bomiz valved catback removes that constraint. With the valves open, the N55 in the F3x 335i and 435i reveals exactly what it's been hiding. Close them and it's civil again. The switch is yours.

Stainless steel 304 construction, dual piping, hand welded. Bomiz electronic valve system with full 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."
