I know it’s been covered a thousand more times than it should. I’ve read 20 years worth of posts and listened to countless YouTube videos. I CANT MAKE UP MY MIND. Billy Boat or Stromung exhaust. I have it down to these 2. Scared the Billy will be too loud, scared the stromung will have me wanting more. Sell me one way or another or maybe I’ll flip a coin.
On the line? Go with the quiet one. You will be getting older as you own the car: less tolerant of noise.
I LOVE the Stromung in my E36 M3
Going to get another Stromung for my s54 z3 and my other e36
Billy boats do sound good too. But I doubt you'd be lusting for more with a Stromung. If you are, do headers.

That’s always a good point to add headers later if I actually want more. I think sound quality is more important than sound quantity. With the Stromung I get hesitant when I read old posts with people saying it sounds stock up until 4K. I want it to sound like a wow what’s that, that’s not a wrx or mustang. Billy boat I’m scared it’ll be like whoaaa wtf is that obnoxious thing. You know? Nervous, nervous, nervous.
Another vote for Stromung here. I have a buddy with one on his S52 Coupe and it sounds beautiful. I'm 31 years old and appreciate the lack of drone.

Went against my elders here. Just installed the Billy. Was very surprised I didn’t notice much difference from stock. Sure deeper and louder at 2k but didn’t notice anything up top. Think it will “break in”???? Thanks guys.
