10 cylinder symphony

There are what, a few "major" header types (Hennessey, Borla, Belanger) and a like amount of catbacks right?

Obviously, the sound is subjective, but out of curiosity, what is the loudest combo (headers and exh only -- keep in the cats) and what is the quietest?

Just curious. All the threads I searched for really only spoke of HP differences, which of course are nice, but I would also like to have a general volume output w/o having to find a Viper with each possible combo...

Loudest with cats in would be headers and straight pipes post cats

Quietest would be all stock for idle & wot and maybe Corsa 2.5" at 2000 rpm in a GTS
