Besides the stock can, anyone know which exaust system (full or slip-on) is the quietest?? I have a 2 bros right now, it makes good power, however it's just too damn load IMO
I also have a two brothers exhaust on my 05 636. The guy that had it before me put it on it. A little loud for my tastes when I want to go out screwing around because it can easily piss the neighborhood, or cops off but it does sound nice and throaty then gets that nice whine when you get higher in the rpm's. Wakes up the half asleep drivers on their way to work in the mornings so I consider it a favor to the community...
Akrapovic on my 2006 is the way I went. Looked on youtube for weeks hearing diffenrent pipes. I really would recommend Akra; classy sounding; not too loud, but sounds really good when you are on it.
