Nice looking ride dude! Bummer about the break down.
Regarding the cat...you can try removing the o2 sensor to see if there's any change in performance, but you really should remove the cat to so see if it's actually clogged. A number of things can cause a clogged cat such as running really rich, oil getting in the exhaust, debris (perhaps running itbs with no filters), and so on. Hopefully others will chime in with ideas because the issue could be a number of things aside from a bad cat.
Installed NST short shift kit today. Damn thing shifts amazing now. Short crisp throws. Didn't take too many pics but here are the ones I did. Extended bolts are 45mm. Fits nice but the boot is a little tight now. Might cut a ring of material off the top....
Nice clean hatch! Along with the nice improvements as well.. Makes me want to get a new shifter too
