Thanks Mike,
Sorry for the delay. I appreciate your sage advice... After pulling out the old exhaust completely, it was evident that there were many issues going on. The rear o2 sensor was broken at the base, the converter was rusted thru on the top side, the muffler - aka "raspy rattle container" was also rusted thru on top.
I bought the Walker Ultra Fit full pipe CAT. All I can say is that Walker is a piece of crap company with no business welding anything. Perfect fit??? I think not. Half of one collector was blocked off!!! Not wanting to reduce the flow by 50% on one bank, I ended up cutting the new one just after the o2 sensor plate (which had two posts that were not even close to being straight) I then clamped the front end to the old down pipe where I cut out the old CAT. Then replaced the remaining pipes and muffler with original Toyota pipes from another vehicle.
I bought a new rear Bosche o2 sensor last night and wrapped it all up. Dico'd the battery overnight and now its running like a champ. I will post the emissions test results later today, with some pictures.
lol you didn't mention the part where your exhaust was complete junk. Betcha it passes now. just don't forget to go for nice drive through the city and the highway first.
