Since its cold out and i really dont wanna crawl under there. Anyone know what size the stock pipes coming off the manifolds are (where the stock cats would be located) ? I hope they are 2.5" pipes because i have 2.5" high flow cats.

Ehh, its kinda weird. I just checked mine since they are laying around. the pipe diameter is 2 inches actually. There is a tapered edge for it to seal good that is 2 3/4 inches.
Here are some pics

my plan is to cut out the stock cats and clamp in (if possible) random tech 2.5" converters in place. If you can check, whats the diameter right before and after the cats on pass and driver side.
Just realized you probably have a single cat since yours is a 94.....
Thx very much.

Yeh, its kinda different cause your OBDII. The piping diameter for the y-pipe should be the same on both our cars (2 inches). My cat starts after the y-pipe with an increaser to 2.5 inches. So your 2.5 cats in the y-pipe might not fit perfectly. But if you unbolt it, a little fabrication should fix that.
