Single pipe or equal length Midpipes

[Mineral///M4]

2015 F82 ///M4 DCT 44k miles

I have a Dinan Axel back exhaust with BM3 tune. I want to add Midpipes however I do not know what style to buy. Please coach me so I buy the best ones to mate up to my Dinan exhaust. I have no plans to go to stage 2. I had a quick 135i w/ a lot of the popular mods, I just do not want to go down that same road again. My burbles are set at 1/2 way.


Thank you,

Watch some videos on YouTube my guy.

On the S55 those two mid pipes can give you totally different sounds and both will mate up to a Dinan muffler with ease.

Single sounds more s55 without the rasp, it's like a deep animalistic tone with very minimal rasp. Single is my favorite setup. equal length sounds like a totally different car, more like the old naturally aspirated inline 6's BMW used to put out. I'm a big fan of the single midpipe especially if it's on stock downpipe I'd never get the EL but just my opinion

Now this is solid advice. I can work with this. Good looking out and thank you.

Tbh they’re very different sounds fundamentally so it’s hard to compare. Single/unequal is a very deep, monotone sound whereas EL is more of traditional and high pitched. Given there aren’t a ton of ELs in the wild, I think the easiest way to compare is asking yourself do you fundamentally prefer the normal S55 sound or do you prefer the N55 sound

I have the AA single midpipe with the stock ZCP exhaust and it sounds great.

I remember reading/seeing somewhere that it's best to retain the midpipe resonator if you're doing an axle back exhaust. Otherwise I think you get drone and/or rasp.

I think it was Tommy Garage.

Single sounds like doo doo.

Equal sounds awesome.

Anyone liking the sound of a single midpipe enjoy your M sounding like a 90s Pontiac or Buick V6

Well this is just great. I was just getting it in my head that I want a single Midpipe and now I have Doo Doo on the brain.

Still these are great facts!!!!

I'm sorry

Here's mine, I might add resonators to make the MPE exhaust sound a bit smoother:
