I’m gonna go with a Hyline off-road louver instead. I’m liking the look and it pretty much fits right over the existing cutout and is pretty affordable (AND MADE IN THE US of A!!)
Got the P0421 code after changing the plugs...cat started glowing red hot. Threw a cocktail of Lucas fuel system cleaner and Cataclean in and have run a couple tanks of premium through it, and knock on wood the CEL turned off. Also added the MorRyde tailgate reinforcement kit that my lady got me for Xmas and it solved the issue of the crappy tire carrier. Just need a new bumper to complete the rear!
Turns out the cat was junk and had completely blown out. Had to drop $1100 to get a new CARB Magnaflow cat. Nice high quality piece with a 50k mile warranty + CA extended warranty on it. Had to replace one of the bolts holding the cat as well because it decided that it didn’t wanna be a part of the Jeep anymore.
