Thanks, so far the only ones that I found without doing the y-pipe would need to be welded in.. not a huge deal as I can do the welding just tacking it in te right location and then pulling it off is a pain but better then what I am getting for $$ on a new one..

 

Well, pulled the cat off and the pre-cat and cat were, well, dust and chunks.. now tryint to find one that will fit my Blazer with the Cal emissions that can be shipped to NY. Anyone have a used one for sale ??

 

Been a long road and after everything is done it wil have new tires, alternator,waterpump,brake calipers, plugs and more and Ihave decided to just sell it once I have it all back and tested out.. Bought it to pull my boat which I sold so now I don't really need it. I have about $3800 into it so I hope to get somehing above 3k or as close as I can ..

 

All back together. New Cat fit great, walker, and it is running good. Were in an ice storm so will be trying it on the highway tomorrow but some runs down the drive, 1/4 miles, and it was nice.

 

Will put 100 miles on it today.. love it will be keeping it but now I have a P0174 code. The cars are new and so is the passanger O2 sensor. Will check to make sure that the exhaust is night and tight, the PVC etc.. but would the O2 sensor behind the cat cause this code?
