I replaced the cats on my '05 LJ for the 2nd time today so I thought I'd share some photos for comparison.
Eastern Catalytic 20379 49 State Catalytic Converter
MagnaFlow HM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 93649
My experience with Eastern Catalytic was not good. About a year after installing, I found that the hanger at the 3rd cat had ripped open the tubing. When I inquired about a warranty claim through Rock Auto, they required that I purchase a new system at current cost and then ship back the old system to see if it qualified for a warranty replacement. Rather than buy the same junk again, I went with MagnaFlow. Though 2X the cost of Eastern, the MagnaFlow cats are very nice and similar in design to the OE system.
With the MagnaFlow cats, the 2 pieces join in front of the oil pan, making for an easy install. I also have the MagnaFlow Cat Back Exhaust that they make for Quadratec and everything lined up perfectly.
