where to buy V style quad rear diffuser

looking for a v style rear diffuser with quad opening to go with megan supremo dual exhaust.

I know they are all over ebay and fitment is hit or miss. Does anyone know of a seller they went with or have experience with that they had good fitment with? Thanks!

That's a hit or miss as well as I've seen guys have fitment issues after being recommended to a certain ebay seller or site. Mine is from CNAutofan and tho it wasn't 100% fitment i was able.ro make it work

most aftermarket parts will be hit and miss with possibly need to trim things as needed for a good fit

Here's a picture of mine. Fitment was probably 90%. overall it's been on the car for awhile now and hasn't popped off, yellowed or faded in any way

I don't have comfort access. I've heard from other's that most lose their comfort access when installing most aftermarket diffusers

I lost my comfort access with the carbon diffuser. Not such a big deal, just use my hand now to open it like any other car.

Smile F10 Diffuser

Good evening - If you're interested, I have a new OEM F10 M5 diffuser, unpainted, which may work for your F10. I can send pics if you like...Tom

I honestly don't know. sorry. my assumption would be no due to 2 completely different rear ends.
