I am the guy who likes having a sleeper, so I’m not looking for straight pipes or the BMW PE. I leave every morning around 5:00am and don’t want to wake all my neighbors on a cold start and drive off. It seems pretty well documented the PE is not good with headers.
So I’m looking for more “quiet power” which I realize is a contradiction lol.
Based on some reading I was leaning towards deleting the secondary cats and adding the AA Gen 2 muffler. From what I’ve read the AA Gen 2 is fairly quiet compared to the PE.
Then I was thinking of keeping the stock resonator but I see AA also has their own mid pipe with a resonator but I’m not sure I see the value in it.
Here’s a clip I found of a forumer with the complete AA set up AA Headers>AA Mid Pipes>AA Muffler and I actually think it sounds good but im wondering if it’s probably too loud for what I’m after. Hard to tell from one video...

I would leave it alone if you want quiet and sleeper. Headers already make the car sound meaner on higher RPMs .
Secondary cat delete will make it a bit louder , also smelly , you could try that first before adding an aftermarket muffler on top of that
Now , if you want more engine noise , like sportier sound coming from the engine bay , I would recommend doing the charcoal delete and k and n filter drop , it will mix very well with the headers making it like a sporty car and it will also add a bit more power and responsiveness. Is also a cheap mod ( under 100 bucks) that you can do yourself. If you want a bit more aggressive sound afe intake is an option , expensive option if you ask me .
As per mufflers , check out the magnaflow , there are a few videos on youtube, it has a deep sound . I heard it in person and it actually sounds pretty good.
I think the PE muffler is the quietest out of all the "aftermarket" mufflers out there.
