Searching for 70mm bolt-on exhaust tips

Considering the new Dinan exhaust for the M2C, but not a fan of the tips.

I believe any bolt-on in 70mm will work.

Ideally, I'd like to find something similar to the BMS replica black-chrome slash cut's I currently have on the stock exhaust (see below):

Any suggestions? Not a super huge fan of carbon, and I think I like the look of the slash cut. Been searching today, but my Google-Fu is weak.

TIA--

The Dinan tips definitely look a little unfinished, and I think it would serve them to offer something that looks more factory, but just a little beefier. Although you mentioned you're not a fan of carbon, these could be a possibility:

I haven't seen any photos of anyone running these, or any other tips with the Dinan exhaust for that matter. Please post photos of your future set up!

I got the Dinan exhaust with the chrome tips. They look a little too big for my taste and I am looking to change them out as well. I contacted dinan support to inquire the ID size and they mentioned the ID of the tip is 3.386 inches so 70mm won't fit into the dinan exhaust.

This is what I got from Dinan_Engineering via PM (edited for clarity):

1. Tip length is 3.75". If including the neck where the clamp sits, add an additional 1.378" to that length.
2. Tip ID is 70mm.
3. Tip OD is 4".

I have the Dinan exhaust with the black tips and before I purchased I was sure I would swap them out but they have grown on me.
Depending on how much you are lowered you may need to be careful about the new tip length as the bottom of the stock tips already rub going up a steep incline.
I'm low enough [max low on Ohlins] where the stock exhaust ball-sack also rubbed going up steep inclines like my driveway.

Well, the tip search is on (permanent?) hold--

Just got the email. The Dinan exhaust slipped another month..... AGAIN.

Now they're saying Feb 19. Which is (coincidentally, I'm sure) exactly a month after the last date that I was given.

They're selling a fiction as far as I can tell.

Hmmmmm.

Mine took 4 month back in may 2020. Dinan is not the same company after it was sold.

ARM motorsports makes a 90mm tip that comes in silver or black. They are held on by an allen screw so they fit a variety of exhausts. I think the black ones look similar to Dinan but <$150. I had them on my F80 and moved them to my M2C.

Do you know if these tips will fit a OG M2? Are the diameters the same as the m2c?

The thing i like about these more than push on style is you can determine how far they stick out and tighten them down. So if you get a new diffuser, you can move them slightly.

Thank you. Those tips looks perfect and a little smaller then the Dinan.
