[M235]

Anyone know or can confirm if the M2 midpipe fits on to the M235 MPE? i don't see any reason why that would not work...but I'm not a mechanic.

Just wanted to see if anyone out there knows of this setup. I'm looking for a throatier/deeper sound. A buddy of mine has a full turbo-back setup and that sounded kinda LOUD for every day driving....did sound deadly though

I have a catted DP and an MPE...not looking to go resonator delete so I'm hoping the M2 resonator pipe dos the job and give a nice M2 grunt to it.


your input is much appreciate...

the part number looks different between the F22 and the F87, but diagram looks almost exactly the same... could be interchangeable. but I doubt it'll be much of a difference...

on another note I just installed the Catted DP from Fabspeed, but have a stock muffler. I heard abit increase in noise and "pop" from the exhaust inside the cab but nothing major... if stock DP and muffler is 60dB this would be like 67dB......

how does your setup sound? any video? im looking into getting a MPE or a M2 muffler to install...

[M235]

exactly..it looks like it can fit, but is it worth it? theres no point if its going to sound more or less the same.

sorry no video at the moment. the setup sounds really good..its pretty much a louder OEM sound and you can hear the turbo a little bit more.. there are plenty of youtube videos with this setup.

M2 muffler is not worth it in my opinion... get an aftermarket muffler like AWE Tuning or the MPE..i prefer the MPE because you get the valves in the muffler, helps with noise reduction when your in comfort mode. other brands also have valve control such as Meisterschaft or Armytrix.

I guess the MPE is the budget valve using existing wires.... have you ever heard the muffler delete from fabspeed? It's hard to judge sound from video... is it MPE that much louder? I'm debaiting bttween those 2....

The 2 mid pipes are pretty much identical and i dont think the sound will change.
the MPE for the M2, actually removes the Resonator - that whole exhaust replaces the muffler and midpipe.
I believe Dinan show cased a video on here with their resonator delete kit with a Dinan muffler and Stock exhaust if i remember correctly - do a search, im sure it will come up.

I actually do like the resonator, keeps the rasp down, I wonder how much different is the stock m2 muffler to the MPE sound... if installed on a m235i

MPE is noticeably louder...buts not considered very loud over all. Muffler delete is loud... too loud for me.

i think they are probably identical since the M2 MPE resonators are removed too. yeah i know of the dinar resonator delete pipe...thing is with videos you can hear the tone of the exhaust but won't really know how loud it gets until you hear it person.

i found a thread there that shows it can be done, this guy got a bootmod3 tune with an m2 midpipe

thing is every exhaust brand out there removes resonators when developing exhaust systems including the M2 MPE as mentioned...its actually the way to go if your looking for a nice exhaust setup.

Now i think best non rasp sound setup would include a catted DP, resonator delete and a muffler (MPE)....from what i understand from others the rasp increases with a catless DP.

So removing the resonator makes is less raspy?! I thought it was the other way around...

I though so too

removing resonators results in a louder exhaust note with a tad rasp but thats normal, not even sure if its even considered rasp... its part of having a full turbo-back exhaust... although you shouldn't be getting real rasp when you have a catted DP + muffler box opposed to having a catless dp + muffler delete...now that would be raspy.

I have the MPE and Wagner catted DP with resonator removed. There was not a huge difference in sound without the resonator. I just had a local shop cut the resonator out and weld in a piece of stainless. Took about 20 minutes for them to do and it was a lot less than a mid or delete pipe.

How do you like your MPE? Compare to a muffler delete?

wow I'm surprised...thought there would be a significant difference in sound. in that case maybe theres no need for a resonated midpipe. do you have any sound clips or videos ?? could not any youtube videos with that setup.

your resonator delete solution sounds efficient..:thumbs:... i will consider it.

Here is a link to a short video with the exhaust sound. It is in sport mode which has a nice burble. In addition to the resonator delete I removed the connector to the flap valve so it is always open. The JB4 will do this, but I made the mod before getting the JB4 and didn't bother plugging the motor back in.

One thing that was really interesting I hadn't noticed before is that just starting the car, putting in sport mode and revving the engine there was no burble. Had to put it in gear and take it out to get the burble.

Sounds really good and not hearing any rasp. Im sold.. will probably be going with that setup

I didn't know the JB4 disconnects the valve flap? how does that work? i know that JB4s can disable active sound (ASD)

Yeah i know...you have to wait until the car really warms up or you can just leave the car at idle for about 5min for burbles to kick in.

[M235SDCA]

Wow I did not know the JB4 could disable the ASD. I'll have to do this, since I made a coding change but it does not seem to get rid of all the fake noise. Anyhow the CAN flap control is just before you go through the main function menus. Holding the stalk BC button for two seconds will control the flap, while continuing to hold gets you into the menus with the maps.

There is a good video here that shows the valve control and then the maps.

found it! can't believe i never knew about this.

To disable ASD... Refer to the video that you posted above, starting watching from about 1min 52sec... the dude says menu 1 on the left side is for active sound control.

i think i read some where that active sound control on jb4s does not work on 335s and 435s but work on the M235. there is a list of map menus when you scroll down under the video...it says that menu 1 is "not used for this model" but it actually works on the M235.

[M235SDCA]

Thanks! Tried and works great. Can't believe that I watched that video a number of times and didn't notice that.

[M235]

Now worries. Same here lol.. dont know how i never noticed can flap control 👍


I think it sounds better with ASD disbaled.

[Dylan86]

Sorry for the OT question.. Is the video showing the ASD disable on page 1? Saw the E92 guy's video, wasn't sure if it works the same for these cars? Haven't tinkered with mine yet, still have snow on the ground..
