Need a cheap catalytc converter replacement.

also just curious, where did you end up ordering it from?

Advance Auto Parts is the only place I could find with a close enough length of pipe to work. Since I'm missing almost 30 inches of pipe. Most places only sold 18 inch pieces or 10+ foot. Advance Auto had a 6 foot one so I'll have to cut it, but it's the best I could find for the price. The 6 foot flexible pipe and 2 clamps ended up being $30ish, which is better than I could find anywhere else. As far as the o2 sensor goes I think it's 20 gauge from what I found online so I might have some extra 20 gauge wire sitting around somewhere. The parts should be coming in today so I might cut and throw on that pipe this evening and see if I can find some wire and give the o2 sensor a go.
 
Um I've been running w/o a cat for almost 3 months. What are the harmfull effects of doing this?

Dude you live in OKLAHOMA. Just pipe it through. Thats exactly what I did when my cat got jacked! We dont have smog testing like Cali. Ifr anything it can be a temporary fix.

That's what I'm doing when the stuff gets here today. I'm mostly just trying to figure out the whole O2 sensor thing now since they cut my front one off and left the rear one. Trying to figure out the exact gauge right now so I can see if I have any around the house.
 
Well I got the straight pipe on and wired the rear o2 to the front plug. It's still pretty loud, but not as bad as before. Everything seems ok so far besides the P0171 code. Is that code because of the o2 sensor?
 
That says system too lean.... is that exhaust leaking around either clamp? that will do it.

I'm sure it is. I have not had a chance to put anything on it to seal it up better. I'll do that tomorrow. I happen to have some exhaust joint and crack sealer so hopefully that'll fix it.
