do you have to remove the cats in order to pull the trans? I have a sc400.. The three nuts on each of the cats a very hard to get to, being that the cats are a bigger round than the flange that the studs are on. In desparate need of help on the subject.

 

I think you might have to......im not sure.

 

boy i sure tell u.. one of the nuts are very easy to get at on both cats, the other ones... well if i started typing what was really on my mind, it wouldnt be pretty lol. WTH were they thinking when they designed the flanges..UGH!!

 

Yeah, I think you have to drop the exhaust from the header back...

 

lol.....they didnt want us to mod it with any aftermarket cats(jk).

 

once i thought i had to replace my cats and i noticed right away that they looked very hard to get on and off

good luck im sorry i couldnt help much

 

Just below the cats are 2 more flanges. Get to em from underneath. Each of those only have 2 bolts on them. Easy to get to and get undone. 14mm IIRC.
