Stupid check engine light-
This one has me ripping my hair out. Ever since I installed the turbo dump pipe, downpipe & cat delete, my cel has been on. I reset it once already and it turned back on after a few hours of running. Is this a common prob? How do I fix it? I'm assuming it's something to do with the o2 sensor, but the car seems to run great.

Its your cat-delete pipe. There is tons of stuff on it, just search for it. Just type in cel fix.

p0431 or p0400
lack of cat. I'm sure nothing serious.
Does it come up when you slow down?

Hopefully it's the cat delete and not the p300 code hehe. I hate that damn code! Cat delete just goto autozone, spend 2 bucks on a pair of 18milimeter spark plug defoulers. Drill one out with a 1/2 inch bit. Screw your o2 sensor into the drilled defouler. Screw that defouler into the other defouler and then into the pipe. Wala.... it's worked for me so far for like 4k miles.
