what kind of mufflers?

I've looked at this thread and the one below.

It is true that what sounds best is a matter of preference. IMO, what makes or breaks a system is the presence of a crossover pipe. The sound clips I have like have all had either an X or an H-pipe crossover. It takes the "rap" out of the pipe at higher rpms. I'm thinking that maybe a couple of straight-through resonators and an H-pipe are all I need.
