This is a deal killer for Dinan when most of our sales come through dealerships who automatically update to the newest variant. The result is every time you go to a dealer it would get updated and the tune would be lost. Instead of just reflashing it through OBD2 you would then have to send the DME to get bench flashed again. A completely OBD2 solution that doesn't require the DME to ever be removed is what is required in our model and that doesn't exist (yet).
Is this only G20, or all B58 cars?

Design is finalized but it requires new bulkheads to be manufactured so we are at the mercy of of that process currently. Typically a 6-8 week ordeal for that component. Assuming all the other pipes and what not are in when those arrive, we are looking at about 2 months out. This is assuming everything goes as it should though, which it rarely does, so I wouldn't put money on that or anything.

Damn that sounds clean! Expected gains?

Couldn't say. Still in R&D (tweaking a small drone spot). Once that is finalized and quotes for kibbles are returned we can estimate an ETA but even then its a pretty wide guess as vendors can be "difficult" at times. Typically not until everything is in house do we feel comfortable with any kind of ETA.

Power gains will be minimal given that cats are still intact. Best guess would be in the 5-7HP range.
Is there a reason you guys never invest in downpipes, more warranty problems associated with these?

Can we hear a sound clip of a Dinan exhaust on the G80 M3?

Looks like the exhaust tips were not squared like they come stock...the M340i's in Europe have the normal looking exhaust tips and look much better. Hoping this exhaust will not utilize the squared tips...

G80 hasn't been revealed yet, let alone released. Ask that question next year around this time.

Sounds just as good on the B58 as it does the N55.

The M340i in Europe has the same exhaust tips as the US ones, i.e. a non-round, trapezoid form.

Interesting, I thought the pictures I've seen have been normal looking exhaust tips? They were blurred in the video but from what I gathered it looked rounded. Think that will look way better in my opinion.

Yes, X3M/X4M exhaust (among other things) is under development as well.

Always. At a bit of a road block the same as everyone else but we have a ridiculous amount of resources (between numerous sister companies) trying to find a work around. Wish we were still around you Barry. Could use the xDrive for some development (our car is RWD)...
Where are you guys located out of?
