335 exhaust on 330

m20b25 · 12-23-2013, 05:16 AM

Morning chaps

I was planning to put the dual exhaust from a 335 on to my 330

Could anyone confirm whether anything other than the below that needs to be changed or moved. I have:

Rear 335 hanger plate for behind the bumper
Full 335 exhaust
Dual hole diffuser
Blanking plate instead of storage tray under the boot.

Is there anything else that needs to be modified to do with vacuum or anything? Saw this referenced on one post but not another

TIA

did you manage to get this conversion done. I am wondering the exact same thing on my 330i but looking under the car it doesnt look like there is any room for a twin exhaust on the other side?????? Help!

Didn't bother in the end!

Yeah, you will need to unbolt the rear plastic storage bin and either replace it with a 335 one or a just a plate.

Some people here will just say to have a custom exhaust made that works around the storage bins but I'd want to do it oem.

I'm doing my exhaust next week, will fit single box as per pictures

The lower part of the rear bumper valance will wobble like crazy in the car's airflow if it's not secured (which it clearly isn't in the pictures).

What's been removed there that the bumper attaches to?
Sorry not familiar with the underneath of my e92 (330d)

The twin turbo car's cross member has small brackets that the bumper valance screws to.
