Another update: Sound is absolutaly amazing.
Gear change fart is like an explosion... crackles when letting go of the gas is insane..
Hurt my ears in a tunnel with the sunroof open

Anyone have experience with another endpipe + 200cell DP?
The M-performance exhaust don't have any valve/flap so the cold start is brutal.

Would the AC Schnitzer or Armytrix endpipe with flap closed be more quiet?

Had a akprapovic sport catt dp fitted for a while now. I am not getting any cell. The sensor position is moved vs original dp. Perhaps beacuse of shorten distance. CeL dont come up .

On their website says only m140i and 240i but fit fine 540i .

Sooo.. Tuning done

I don't know about USA, I see you guys mention 91/93 RON
Here in Sweden we use 95 or in some cases 98 RON

I use 98 RON of course. For my car and my MC

Stage 2, 200cell DP with tune result?
448hp & 676nm

Our 93 pon is similar to your 98 ron fuel. Those are some good numbers. Are you running a custom tune? Are you planning to run e30 tune? Would love to hear it 😎

I have AC SCHNITZER EXHAUST fitted and yes it is quiet when the flap is closed. I would suggested you not to change the cat back but instead get it remapped and they will disable the cold start from the ECU.
