Not happy with Remus exhaust sound

I'm running a full Remus Race (including mid pipes) and it just doesn't sound good. My old M4 used to crackle on overrun with an MPE, this just doesn't do it.

I am still running OPF, is it worth removing these for straight pipes? Or should i try a different exhaust first?
I'm not looking for a quiet exhaust, and i'm running stage 1 tune so no issues with cel.
Any help is appreciated.

AA Midpipe
Remus Race Back
No OPF
Catless DPs

Best an M2C is gonna sound imo
Remember, despite how fun the car is, it will never sound objectively "good" simply due to the engine setup

Wow. I have AA mid and Remus Race Rear and it is pretty loud to me. Cold start is amazing but my neighbor won't love it.

I imagine with catless DPs it is not subtle!

I'm not terribly familiar with OPF since we don't have it in US. Is it not part of the mid-pipe? One key difference with AA mid is that it is a single large pipe vs two on the Remus mid.

Sound wise, I am happy with the AA Mid and Remus Race rear though I might have been better off with Remus Sport rear and the AA Mid. I don't this the Remus rear is your issue. Probably the mid and maybe OPF.

I've only heard the setup once in person, but I don't have it.

My M2C is AA midpipe and catless w/stock Axelback
Even that is astronomically loud when you're on it, but the tone could be better

Add the Active Autowerke midpipe to your REMUS exhaust

Your problem are the OPFs, not the Remus. If you remove them maybe you will desire a center resonator.
