I'm looking to replace my catalytic converters with some high-flow metallic spun ones, but I can't tell if there are two cats (front and rear) per side or if there are one per side on the front near the O2 ports and one resonator per side near the rear. Anyone know? Also, is the exhaust tubing 2.25"?

 

I'll answer my own question...lol. There's four. Two in the front and two in the rear.
