Interesting, my stock exhaust rattles on cold start, so I'd expect the Dinan to do so also.
For reference - I'm running a CG Precision catted DP and Mission Stage 2 tune through my stock muffler and zero rattle issues
Still waiting to hear the video btw

Please clear some of your PM's.

At first I had an issue with getting the tips pushed in, but after driving it seemed to warm it up enough to where I could easily slide them in or out.

I'll be making a video soon!

Bump bump. Waiting on the video.

I'm really thinking of grabbing the exhaust. It shows that it's out of stock till August now, which definitely sucks. I would buy it but would hate to have an issue like this pop up.

I’ve had the Dinan exhaust for about two months now. It didn’t seem to rattle on cold start when I first got it. It then started to and seems to be getting worse, actually. I got the same standard response from my dealer that was posted already about it being “normal” when they reached out to Dinan. Since it seems to be getting worse, I’ll shoot a video and send it to Dinan and the dealer for further evaluation. I don’t think it’s the heat shield but I’ll have them look anyway. It’s embarrassing AF, to be honest, when you start your car with that exhaust it makes such noise. It’s a great product, sounds amazing and looks sexy, but that rattle is a kill.

I’m getting an F97 as well and they just released the exhaust for that today. I’m on the verge of pulling the trigger and ordering it but I’m head shy this exhaust is going to do the same thing.

BTW, it’s only doing it on cold start. But it just sounds like ... ugh.

Doesn't seem normal for a Dinan product.

Seriously hoping this will be ironed out by the time mine arrives in August. I had a similar issue w the MPE in my F30 and had it replaced 3 times per warranty from excessive rattling.

Let us know what you find out w this please!

Get a video and send it into support (either the ticket system on the website or direct to support@dinancars.com). Make sure to note it's just on cold start and if it's only 1 side or both. Which dealer installed will also be helpful if we need to reach out to them. If it's as atrocious as you say then it's not normal and probably something that needs to be tweaked and in the worst case replaced. Number of things to try before we get to that point though. First step is the video and then we can go from there...

Dinan's support one these forums is def reassuring. If anything does pop up they seem to be willing to help out ASAP!

Can't be said for a lot of other vendors these days unfortunately

Hi Dinan! By any chance is there an update on new kits? Awaiting my replacement and I think we're at the 7 week mark. Please let me know when you can!

Did you order from Dinan directly? I've been waiting 6+ weeks already and may just go with the MPE if this keeps getting pushed back

Anyone else have their order delayed further too? Ordered mine in beginning of July and was told it would be in stock on 8/5 but has since been pushed to 8/21.

If there's another delay I may end up going w MPE and won't need to remove the Dinan and resell when I return my vehicle at lease end.

Delays everywhere. I waited 10 weeks for a carbon spoiler from Autotecknic. I was told 4-6 still didn't receive it after 10 weeks so I canceled. Wont be doing business with them again. Shout out AA Concepts for coming through.

Yeah I get it! I know there's a few others on here also waiting for theirs to arrive. Hopefully not too much longer

Working on getting a better video up for you guys soon. Shot one with a burble tune on there but it was just way too much popping to even really hear the exhaust note in the recording.

Here's a few photos though. I've had the exhaust on for a couple months now and it's been great. Really can't speak about the difference the valves make enough. It's night and day difference in terms of volume.

Yep, saying stock will be in around 9/5. This is getting old real quick. I can understand a delay due to Covid but not several months?

I talked to the dinan guys at the MPACT booth. he said Covid-19 was one issue but when they got purchased they decided to use a different supplier the same supplier as their Flowmaster exhaust supplier. They were having quality issues so have not switched back to their original supplier. They said was probably the delay. Sucks. I am ready for sound.
