ok so i have an e90 335i 2008. i bought the car like this last year with this rear bumper. i dont know if this is a e90 or e92 rear bumper i have with diffuser. this a-hole before me just cut the diffuser to fit the exhausts, and it looks horrible! i need help finding a quad diffuser for my car. everywhere i look or "search" its all for e92 and none for my car, unless mine is the e92? i know i dont have mtech kit bc my front is reg bumper. need to find quad diffuser! btw the exhaust brand is "bastuck" and i dont know if this is the lce or pre lci bumper? help
