I'll copy and paste what I posted in another thread.. and I found it okay. typed: "header torque"

----------

actually... almost all the bolts have torque specs.. its so you dont strip the threading..

ESPECIALLY the manifold bolts.. cuz the top two are easy to strip.

EX:

the 2 bolts on top are 23 lbs.ft or 31 n.m

the 3 nuts below are 23 lbs.ft

the heatshield bolt in the middle is 17 lbs.ft or 24 N.m

DX/LX/HX:

the 2 bolts on the top are 23 lbs.ft

3 nuts on the bottom are 23 lbs. ft

the TWO cover bolts for the heatshield are 7.2lbs or 9.8 N.m

the two bolts on the bottom that holds the header to er... hmm something. lol. (not the two bolts that hold the header/cat to the downpipe) are: 33 lbs.ft or 44n.m

for the bolts with the springs on them that connects the headers on the downpipe both ex and the rest:

16 lbf.ft or 22 n.m tighten the bolts in steps, alternating side to side... this will ensure that the header will be fitten on correctly.. without one side being too tight and exhaust leaking...

I think thats all for the header.

oh wait. oxygen sensor 33 lbf.ft or 44 n.m
