I believe the two outlet pipes are 2.5". Can anyone confirm?
Real mystery is what the diameter of inlet is? also 2.5"?

Not sure of what mufflers I want to use yet. I have a Magnaflow axle back now, and it sounds pretty good, so I may just keep those.
I have to start with the Y-pipe. From there, I was thinking X-pipe, two 12" resonators, and two mufflers.
