The one you linked has trapezoidal shape to fit the 340 exhaust. Your 330 exhaust will be in a bigger hole and look a bit off (my opinion).

Ikon rear diffuser you have to trim some brackets to make it fit perfectly but nothing crazy came out good, pardon the dirty car

Adding a little after I looked at it some more this diffuser comes out some more than the stock, so the tips actually are way more flush now.

I tried to delete my comment. I thought you were commenting on my comment. I have a m340i and I ordered on from China that i linked. They said it fit the euro version but hadn't tested the US version. I didn't look at who you quoted when i replied ..lol

Yeah, I'm not sure if this will fit our M340i. The Chinese versions of G20 all come with square exhaust but apparently it is a difference size of square exhaust compared to our M340. I would contact seller and make sure this fits. I mean if it does that carbon fiber will look sweet. Cheers!

Might have to just get the Dinan quad setup if this is the case🤣

Can you show the link where can I order the 330i diffuser, the one you have look so good.

Strange, they charged $1000 ship to Canada?

I just send a email confirm with them.

fitment is on point and no issues at all, not bad for $169

Has anyone found an AFTERMARKET version of this design but with carbon fiber fins? I've looked everywhere and only see the OEM version...

Just picked this up for $440 shipped with code BLACK from AutoTecknic.

Will have photos once car arrives and I can install everything.

I have the 340 one coming to replace my 330i one and round tips. Was the process straight forward that you did please, love to hear ?

Don't know if it has been mentioned, but try CMST Tuning. I have mine on the way 🤗

Should I be concerned that the little drop-down compatibility tool says this is not compatible with a 2021 340xi?

Got my CMST tuning diffuser installed this past weekend

Oh nice! That's one of the best I've seen so far!

Hi,

I wanted to go with Gloss Black Diffuser. I got one from an eBay seller & no joy -- didn't fit correctly & to boot the dual tips were also no-gos

I found a great Diffuser from Kiessport. Though it was matte, got it painted -- not only does it fit great, the vanes/fins give it a mildly aggressive look.
