Hey guys.. I have a 2015 435i xDrive with M Performance exhaust and MPPK. It's currently stored for winter but I want to start looking at what I can do to the MPE to extract more sound from it and get louder burbles obviously (Cause we all need louder burbles in our life . Any help would be appreciated thanks

Yes.

I have Fabspeed/MPE.
No CEL & I wouldn't want it any louder.

If you're looking for obnoxious noise, you won't be satisfied.
If that's what you're looking for just go to a cheap muffler shop and have them run a straight pipe.

im running catless mpe and jb4 and it sounds amazing... not too loud on normal and idle but really opens up on WOT and shifting and the burbles

I’ve heard a lot about this setup it’s what I’m leaning towards. But what do you do about the CEL? Do you get one?

i have a jb4 wit a cracked app so i can still delete the CEL from the DP...

will be moving to mhd flash and they have the ability to delete the code as well.

Ecs came out with a catted downpipe and I believe they said the check engine light doesn't come on

No, just the CEL for cat.

I have a friend for that NY allows for 1 monitor in not ready status but I haven't had the chance to test it out myself.

Delete your resonator depending on how long you're gonna wait for the DP.

I paid 100 and if you want to put another one back on it'll be another $100 to buy the resonator Im guessing.

Do you hear a big difference with a res delete?

I did yeah, cold start will be louder, so be ready for that, burbles up in volume, and 3-5k rpm got louder. But what do you expect... you're removing resistance in the pipes . But then I wanted it louder so I got a catless DP on top

Now it's a little too loud, but the tone is beautiful and exotic to me. I'm gonna enjoy it for a while before getting a catted DP

Nah brah I had mpe/res delete and I had plenty burbles... even the very loud ones... not the snap gun shot ones like catless, but high volume poppers
