sound good, do like my AA mid's with stock rear muffler though seems deeper. Regardless this looks impressive, would like to hear this in person.

Does sound decent. Do we know when it'll be released and cost? Not on their website yet

i reached out to them this morning. they told me that due to production delays, it might be towards the end of summer.

Thanks for sharing I haven't seen this video before. I gave them some feedback a while ago, hope it comes in under 2k.

I would consider it for sure, but pretty disappointed with the 3.5" (88mm) tips. This car needs a 95-102mm tip at minimum

AZ-Wildcat · 06-28-2019, 12:56 PM

Not a fan of the tips, sounds good tho

They are 4" tips. Not 3.5". Just FYI.

mobile23 · 06-28-2019, 05:38 PM

Curious to see what products video 3, 4 and 5 are?!

Bimmer28312 · 06-28-2019, 07:48 PM

AA pipe with this axle back would sound perfect I think

Sadly, i was told that it will not be sold in sections. i believe it will be OPF back.

Ugh.... Well I'll have to see how good their version of the xpipe is. Interesting though they normally just do the axelback. Maybe Dinan in Here can clear things up.

2PUTT is correct. It's OPF back to maintain emissions compliance. We were planning on doing a mid/resonator delete/X-pipe and a axleback separately but BMW's stock design would not allow it without some sacrifices we didn't feel we wanted to make. The biggest of which is there is no real good cut point for an axleback in the M2C. The obvious point is the one small straight section of pipe that is also outfitted with heat shields. Cutting there would mean that the stock system would be forever marred and incapable of being reinstalled at a later date (trade-in, etc). As a result we opted for a one piece solution with both elements included.

2PUTT · 07-01-2019, 04:23 PM

after studying the video closer, it looks like there are 4 clamps
- OBF to Mid/XPipe (2)
- Mid/Xpipe to axle back (2)

mike@x-ph.com · 07-01-2019, 08:23 PM

Sounds good

Bimmer28312 · 07-01-2019, 10:28 PM

So how different is the Dinan xpipe to AA pipe

AA
- connects to DP
- single oval pipe
- no OPF; no resonator

Dinan
- connects after the OPF
- maintains 2 pipe design
- X-pipe connecting to the Dinan axle back

omasou · 07-02-2019, 09:57 AM

There isn't an OPF in US, correct.

Correct! I don't know why everyone (even Dinan themselves) keeps referring to it as OPF back but US spec cars have secondary cats, which are very different than OPF in terms of how restricted they are.

I guess it's easier to say "OPF back" than "secondary-cat back" lol.

Thanks for the breakdown

So does removing the secondary cats negatively impact emissions testing?

Also there isn't another set of O2 sensors back there, right?
