I had a similar pair on a 69 Camaro for about 20 minutes. I sent them back to Mario Andretti directly with a note stating that I couldn't believe how crummy they sounded. Like deer farts through a pillow.
Went with Dynomax Super Turbos instead. MUUUCH better. I'll never use anything else. They have the deep muscle car tone and don't wake the dead when cruising (like Flowmaster).

I run Flowmaster Super 44's with a gear drive and you can hear me coming from a mile away 
I do wish they were a little deeper in tone.

Going to your original question, it depends on which kit from Magnaflow you get. There is one that's not mandrel bent and I think that starts at 2.5" and ends in 2" and then there is the one I have which is mandrel bent and 2.5" all the way through. (see my pics)
I was a little disappointed at first with how quiet the exhaust is at idle, but the more I get on the throttle, the more I like. Freeway speeds are music to my ears (even at 2800 rpms). And as stated, you stomp on it... Oh baby!

I've recently acquired a set of Turbo Cherry Bombs. My car currently has Flowmaster 40 Series on them. Engine is a 355, mild build (intake and cam). Anyone know what the difference in sound is? My car has run, but only to load into a trailer as the carb is crap and the brakes are almost non-existent.

I've had many mufflers on mine and the MagnaFlows sound the best to me. Just get the universal fit in any size or configuration of inlet / outlet you want and take them to a muffler shop. I run 3" in and out and they are great
