Unfortunately, I was not able to find the best amounts of info from my use of the search button. However, I was wondering if anyone knows of a vendor/company/etc. that sells quad diffusers that are for the E92 328i? Most quad diffusers I have come across are either the more narrow 335i orientation, or they are simply for the E90 rather than E92. So, in short, I'm pretty much looking for an E92 328i quad exhaust diffuser, but if there are no vendors who sell these, then I do have several options on what I have been planning on:

1. I can just buy an OEM 328i diffuser and cut it up.
2. I can try to fit an E90 diffuser like shown in the picture below (different style perhaps) and modify it to fit well.
3. Hack up the exhaust (Least favorable as I don't want to butcher my Remus Quad).

The following style is what I've been searching for:


Or, this:


(I don't want to go with too much carbon tbh.)

Also, most of what I've seen are these (again the following is not compatible on the account of the orientation of my Remus quads):


Any info helps, thanks.

I dont think that you will find a 328i quad diffuser as the quad diffuser is meant for a 335i. Maybe someone with experience with the quads can chime in.

That may truly be the case. I honestly don't think there is a market for the 328i quad diffusers. I guessing that it's because of the rarity of the exhaust systems.

I might just go with rigging an E90 diffuser like I mentioned above, but do you, or does anyone else know if the E90 spec diffuser can fit an E92? I understand that the clips may be different, but I'm just mainly concerned over the curvature of the bumper piece.

E90 diffuser won't fit an e92. There's a few people who have gone over to the 328 diffuser who have 335's to either give their car the sleeper look or because they went single turbo. You can either get a e92 diffuser and modify it for quad or buy a quad diffuser for e92. Just gotta fab up a quad exhaust set up.

Use a 335i quad Diffuser and get your exhaust modified to fit it

E90 will not work at all
