Non M rear diffuser on 430 GC

bimmerluver · 06-29-2019, 05:27 PM

Does anybody know where i can buy a rear diffuser for a non M trim? Planning to do quad or just make my back look a little aggressive.

i don't think the non m-sport bumper and diffuser is separable.

if you want a quad or split you'll have to get a template and cut/dremel the other exhaust cutout

Dual side exhaust of 335i/340i is closer to middle of the car than left side in 328i/330i which means that left exhaust cutout is also in wrong position if quad exhaust is installed. Except if it's not made specifically for this purpose. In other words, you need to cover original cutout somehow and then make new cutout in both right and left side of the car.

This is preventing me from upgrading my stock exhaust of 320i Sport line to 335i MPE. There's no clean way to cover my original cutout.
