I've never heard a SUPER 40, but I have 40 series 2 chambered mufflers on my 5.0 Stang and my 77 F150 460 and they sound great!!

You may be able to find sound clips for those and other mufflers in the exhaust forum. Personally I like Magnaflow mufflers. I think the flowmasters make all engines sound like a Cheby but that is just my personal opinion.

Another personal opinion, yes they sound ok, but not worth the money.

One thing you might want to consider is the resonance sound in the cab, if that is not a problem, then go for it. I had 50's on my 79 F-150 460 with duals and the resonance sound in the cab was unbearable between 15 and 55 MPH. Took a copout and changed to the 70 series Flowmasters. But I have to say they are quieter but just not the BIG sound I was looking for originally, but the enter ears prevailed in the end!

To me, flowmasters makes a strong engine sound like it is running under water and exhausting thru a 6 inch stove pipe. Magnaflows are the way to go, they make a engine sound the way the old big blocks in the 70's sounded. Powerful and throaty...

-A rattling vibrating stovepipe with a rubber band and tin can lid tied across the end...

The Magnoflows have a nice low rumble when cruising and a nice throaty bellow when you step on the loud pedal just like an engine should sound.
