probably going to need dual mufflers, I would imagine that you would be best served by a pair of the same muffler as opposed to two different style mufflers.

I would say ask your local exhaust shop, but it's russian roulette based on who you talk to... and experience has nothing to do with that. The most "experienced" muffler guy in my town puts out the worst sounding, oversized exhausts (but his welds are sinfully perfect). But the new kid at our local Midas gets the right sound and size everytime.

here's a pic of a Sprint manifold and a 2.4 manifold next to each other. I don't have a 2.4 manifold of my own, and I do not have a pic of just the flange, but maybe this will help some. (the 2.4 manifold is the one on top)
