Loudest slip-on available for the 1M

I'm looking to make my car a little louder, I wanted to get maddad mids but the shipping from USA to Portugal is 700+ dollars, the shipping is more expensive than the pipes and no one sells maddad here in Europe, so unfortunately it is impossible for me to get them, even though I think that would be the perfect setup for me.
The other alternative is to buy a slip-on, I have been checking all threads available about exhausts and all slip-ons sound very similar to the stock exhaust (even the Akrapovic), at least in the videos. I would like to hear from personal experiences what is the loudest slip-on available as I don't want to spend too much money so I will not go for a full exhaust.
Thanks for the help!

Mostly likely GT Haus due to the muffler delete.

without mufflers that is for sure the loudest, what about the slip-ons with mufflers? Which has the best sound? I feel like most of the people that change the slip-on are always left a bit disappointed with the sound.

Im still enjoying my Remus.
With the mid pipe i got the centre cats removed. Didn't replace the whole pipe itself.
Its louder without being deafening. Makes quite a nice sound too. More tonal. Also more pops and crackles.

Look into the N55 midpipe, basically the maddad pipe just a little less boomy and less burbles. Used to have N55 with Meisterschaft then changed to maddad with Meisterschaft when i was looking for more tone. PM me your email and i can send you a vid of the meister with maddad.

maddad mids unfortunately I cannot get here in Europe, otherwise it would be my first choice! N55 mids I'm not sure as some people tell there is not enough difference. So my only alternative is to get a nice slip-on. Supersprint slip-on , anybody has any feedback? They have a race version, that must sound good and I can get it here in Europe. Is it a direct fit to the oem pipes?

the Meisterschaft slip-on alone is not much louder than stock is it? From the videos it sounds very similiar to stock. Even quieter maybe?

It should be much louder than stock...its just straight pipes from mid pipe back.

100% meisterschaft with N55's.
Had that combo on my M and it was super loud and exotic.

You basically can't get any louder that deleting the rear muffler and mid cats..

Any video? If it is only the slip-on how satisfied are you with it? If the race is only slighlty louder than stock than I imagine that the sport is not any louder.

Meisterschaft is much louder thanks for the videos, but the 1M is my daily so I don't want to go too crazy. I really like the sound it makes stock, but when full throttle the turbos are sucking all the air and I can't hear much of the exhaust noise, the noise is all sucked in by the turbos. Half throttle it sounds great though.

I have also had the eisenmann race exhaust in the past on the M..
Wasn't much louder than stock IMO..

In the end I settled on the Remus axle back coupled onto the N55 mids.. Great deep throaty exhaust with virtually zero drone at all speeds.

Go catless, you'll get the volume of sound alright, I ran an n55 mid pipe w/ the BMWP Y-pipe and a Dinan exhaust and the car was bananas!!! Ended up putting the resonator back on as it was too brat-nasty and unrefined.

I currently run a Remus cat-back with N55 mids, and my results are similar to yours.

Sounds brilliant at part throttle everywhere, no drone, quiet enough with the windows up but loud enough to feel modified. My only issue is at full throttle, the turbo's dull the noise so much it sounds a bit like a vacuum. I'm thinking a nice intake might help with that, if not I may change the exhaust out to something more aggressive.

Actually, I'm very happy with it. The sport exhaust is similar to stock but deeper.
