Just got home a bit ago with my newly installed Dinan system. It is the entire catback set up.
Its tough owning an M2 because any modifications you may want to try, odds are you're the only one in town with an M2. So without getting to check one out in person, I ordered from Dinan. Nice people, very helpful. Fast free shipping.

First impression on appearance- Looks much better than stock IMO. I didn't think I'd like the black finishers, but I do. They look good. Understated yet aggressive. Plus probably easier clean up.

Sound- Obviously much better. I have only heard it from inside the cabin and while outside at idle. Sound is like stock but amplified and deeper. Almost makes it sound cammed a little. Much better rumble at low speed/RPM. WOT honestly, the CTS intake is what I hear most of. Lots of overrun burbles and pops with the whistle of the intake. Bottom line, sounds much more serious. If you think stock is too tame, this may be for you. I almost thought that it was a little too quiet. My wife assures me that she thinks its way too loud. BMW SA's loved it.

I wasn't sure how the comfort mode would sound, with the valve closed. At idle and low speed it doesn't seem to make much of a difference. When you give it some throttle, then the difference is easy to hear. Much more muted. In fact, I'd say that comfort is maybe just a little more tame than Sport + on the stock system. Not much pop or overrun.

As a frame of reference here are a few comparisons to some of my recent rides
M5 V10 with muffler delete--wife says the M2 is louder
M235i with MPE-- Way quieter than M2
STi with DP and exhaust-- Wife says the M2 isn't as loud

Tried to get descriptive for people stuck on the fence about which system to choose

Thank you for the review. I have been leaning towards the Dinan muffler but I am on the fence if I want to spring for the resonator delete at the same time for the fear that it will drone too much.

Have you noticed any difference in drone at highway speeds and/or light throttle?

Post some pictures!

There's no drone, at least what I can tell.

Agree, no drone. In fact cruising in 6th all I can hear is a faint intake whistle at times. No drone, no real exhaust noise at all
