I'm running the 40 series and have grown tired of it. Is loud in general. The 50 is quieter at idle by a bit but the 40 on long rides is what I dont like. It just seems droney after a 100 miles or so. My neighbors **** and moan that my trucks to load when its warming up at 0445. I think my next will be dynomax duals staight out the back instead of the side dump.

I had the 50 series on my 87 Bronco (true duals with headers, 351W and other minor work) and it was way to quiet for me. I switched to the 40 series (not the Delta Flow) and love it.
40 Series (not Delta Flow): At idle it has a very deep melow rumble(not loud). Under normal acceleration it is very noticable, and under WOT it screams like a race car.
50 series: Barely noticable at idle, Somewhat noticable under normal acceleration but you almost had to listen for it, and sounded ok at WOT.
