I'm thinking about an exhaust shop whipping me up a custom 2.5 inch catted x-pipe with some flowmasters on it. I just need to decide between the super 40's or super 44's. Is it a matter of sound preference, or does one sound better on a V6 than the other?
Also, should I have the shop keep the stock 2 1/4 piping all the way down, or bump it up to 2 1/2 like all of the exhaust kits from American Muscle?
I know it's a lot, but I'm just trying to research the best options. And if anyone else wants to offer more input, it'd be greatly appreciated!

 

I would probably do a 2.5" exhaust system with the 40 Series Muffler if I were you! That's going to be the best flowing/sounding exhaust, as far as custom goes.
