You know you can just email the seller and ask if it will fit or if the sell one.

I did and got this in response

Sorry to reply you late. We don't have this diffuser for E92 yet, but we can make it on E92. First around order will need 10 pieces at time and each piece is $400USD not including shipping cost. After that you can order one diffuser each time with $275 not including shipping cost. Because first 10 pieces' price are cover the cost on mold. Thank you.

Well there you go folks, who's in ?

That's tempting. I've been after this exact diffuser since I saw it on JB4 Benelux's car earlier this year. Though I suspect it won't look as good on an e92 since we don't have that nice flare just above the diffuser that the e90's have.

I'm in

One thing I'd be curious about is the availability of 1x1 weave instead of 2x2. I'd love it to match the 1x1 of my roof.

Just bought this as well. Very nice quality piece. Got it for $305 after the eBay 15% off coupon

Just tried installing this on my 335d m sport. This fitment is beyond trash. The tabs do not line up and are facing downwards rather than straight. Do not match up with the factory exhaust hangers at all. I will be partially screwing down the bottom end and will zip tie the rest

I still have yet to install mine lol but plan to do so during winter. Post up some pics once yours is in! I know I mocked mine up and the tabs are a joke, zip ties definitely needed

Any updates on your install? I recently installed mine and the fitment pretty bad. It looks like Roma nailed it with the fitment. I have gaps on the right side and if you're looking down from the top down onto the diffuser you can see and gap along with the tabs.

Yeah fitment was ROUGH. Basically it felt like it only wanted one side to fit. It put so much pressure right next to the exhaust tips it cracked the clear coat/epoxy on both sides. Not too noticeable but def shitty fitment.

I also couldnt get the far left / far right top corners to stay flush. I ended up having to finagle zip ties in there to hold it in place and stop it from popping out. HUGE pia. Looks glorious though

Then I finally fixed my exhaust tips

It does look good! Winning

bsm.m2 · 05-13-2019, 08:26 AM

Looks good man! I'm going to have to take mine off and try to reinstall it again....

You kept your rear bumper on during installation right?

Yeah I left in on during install

I like it, good find!

I just bought this item, and am having different results than you guys. The one I got is so bad I am demanding to get a refund. Maybe there are different versions of this similar product..

Problems with the one I purchased;

- All the mounting tabs are 2x as wide as the OEM mounting slots. The center ones are 3/4" wide on the diffuser and 3/8" on the car. Outers are 1" when the car is 3/4".
- No holes drilled at all for mounting
- Will not flex over the three OEM mounting locations. I removed the center plastic dog leg, but it won't go over the two metal "L"s.
- After trimming all the tabs, drilling holes and cutting the clips to half the length since they are pointing DOWN, it will only clip in on one side. Pushing anywhere else causes the entire thing to pop-off.

The resin has cracked everywhere, the one side completely shattered when it "popped" off with so much force it made me jump. That was the last straw and I gave up on this bloody thing.

The finish on mine was quite bad as well, lots of resin high and low spots, blotches and long creases. I wet sanded them mostly out after 2hrs and buffed it before I even wasted time trying to install it.

Disappointed... Love the look of them online.

Any other alternatives out there?

Thanks!

is there a way to cover up the right side?

Would look weird. Seize the opportunity to get a dual exhaust made.
