Let us know how it goes!"

My Honda did that, with the silencer in on the apexi exhaust 20 years ago. Not acceptable here.

I should have specified that was the MPE for my F30. Was a constant rattle issue w the valves. I eventually gave up on getting it fixed.

Still would take Dinan over MPE given the choice. Sounds and looks better IMO, plus customer service is a hard thing to come by these days it seems. Dinan does a good job of that from what I can see

Bummer man. That's the same exact rattle sound I hear on my exhaust only yours sounds worse. I'm taking mine back as well to have my valves checked again. I discovered that even after cold start AND in Sport mode, I still get a little bit of a rattle, although not nearly as bad as yours.

Sounds way worse in the video but yes bummer at least is Dinan is being very responsive and professional

I have no idea but it is going back this week for the fix. Dinan and Carbahn are in communication so I should be good to go. I'm chalking this up early adoption growing pains....

Well glad someone has had a good experience. Meanwhile I seem to keep getting the run around. Hoping this gets worked out or I'll have to go with a different exhaust.

Glad it's been smooth but dang... was it so bad that it was not driveable? Why not take it back in when the new exhaust arrives? I am definitely on pause now with purchasing this exhaust. Although the customer service seems to be great, this is my daily and I don't want the headaches..

It's totally drivable but it was just because one of my other cars was there and I dropped it off when I picked up the other one it will be done this week and I have other cars to drive

Same. Andrew mentioned 4-6 weeks. He was adamant that the cold start rattling will not go away, but hopefully my rattles after cold start will. Fingers crossed! And thanks to Dinan for the great communication and helping me diagnose this!

Wanted to post an update. I've had the exhaust on for a few weeks now and haven't heard any rattling at all.

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!

Interesting. I believe you're the second person who hasn't heard any rattles at all. 50/50 split so far.

Interesting, my stock exhaust rattles on cold start, so I'd expect the Dinan to do so also.

Really? I never heard my stock exhaust rattle prior to the switch. Must be hard of hearing on my part.

For reference - I'm running a CG Precision catted DP and Mission Stage 2 tune through my stock muffler and zero rattle issues
