haha, yeah, luckily i had no left over spare parts, drove it around, and it seems to be holding up alright, got in 4 full-time, and that worked well, drove it to the shop and had them weld on a new cat. headers should be next

t-case temp is about 40 degrees cooler (runnin at 230 to 260 F now instead of 270 to 300 F) shifts great too, but i haven't gone offroad yet though. cat is runnin round 230 to 250 F now, but i still have some hot spots in the exhaust. the expansion bulb right at the front of the tranny is runnin round 428 F, that's effin hot imo. so now i wanna get some headers & run some new stainless pipe to see if that fix's it.

i didn't either, and i can't make sense of it really, but i noticed while shootin temps, that all the hot spots were on the old rusted pipe. i guess it lets the heat through easier to the surface of the pipe

(granted the cat was a top of the line cat that was over $300, but that is still way too much for me to justify it)

yeah, but i know if i woulda hunted on ebay & google, i coulda gotten the same cat for under $200, then just hacked out the old one, and welded the new one in. i think i will do the rest of the exhaust my self. the only part i will dread is the headers, but it will be manageable i'm sure.
