91 LS400 cats (catalytic converters)
I have a 91 Celsior (LS400) and bought the S&S headers. the 3-bolt flange on the headers is the wrong size and the tube lip on the cat is a bigger diameter than the header exit, so it wont go together.
My options are:
1) put in de-cat pipes
2) get some flanges made & put in some universal high flow cats
either way, i need to know this info:
the measurement from flange to flange? (length)
the diameter if the tube lip on the 3-bolt flange side?
Also, it would be a great help if someone could trace the flanges and bolt holes onto a piece of paper and email it to me (or post it here). you will need to draw a 1" reference line on the paper so i make sure it is printed the right size. that way i know for sure it will fit.
I would greatly appreciate the help.
thanks
