I want to get rid of the grey diffuser that comes with the M-Sport 5 series models. I've bought 4 different ones from Ebay and none of them have fit, I'm getting pretty tired of returning them. Has anyone with the same car as me changed out the diffuser for a gloss black one, if so, can you send me the link? I'm aware Ebay is not the best place for quality parts but all the high quality diffusers I could find were carbon fiber or meant for quad tips. Please let me know if yall know where I can get a gloss black diffuser for a 2021 BMW 540i that will fit well and won't look weird with my stock rectangle tips.

Not sure what style you are looking for, but this is gloss black and fits well.

Correct me if I'm wrong, but I think OP has the stock 540i exhaust with trapezoid tips - not the rectangular 550i or 540i MPE ones. What was wrong with all the ones you returned OP?

Here is some I could find.

I actually ordered this one and when I got it I saw it was not meant for my exhaust tips so I returned it, but it did seem good quality compared to the others.

You are correct, I have the stock 540i exhaust. I ordered 4, one of them was the one Joe sent which had nothing wrong with it, the holes were just too big for my exhaust tips. Another I cancelled before I even got it because they messaged me telling me they had gotten a lot of feedback saying it didn't fit right. The clips on the other 2 didn't fit on my car at all, on one of them some of the clips didn't line up with the holes and on the other they were too small so they didn't actually clip on they just went in the hole. I think I am just going to wrap my OEM one because I'm tired of ordering ebay diffusers and having to return them, but thank you for your help.
