The new header is in place. When torquing the top 9 bolts to final spec should I tighten outside -> inward or inward -> outside?

Also any advice on removing the o2 sensor from the stock pipe? I have a torch available to me.

 

ABout the bolts. I just tigetened them all a little at a time till tight then torqued them. ANd the 02 is a pain in the ***, I put the cat in a vise, then used a wrench. I dont think you need to torch it. Ryan

 

Alright I'm going to tighten inside->out as shown on this page: http://www.home.mpinet.net/t-hero/Headers!!.htm

o2 is going to be a bitch. No vise here.

 

Just use the old foot-vice. Works everytime

 

All done. Thanks guys! Everything seems alright. No check engine light and didn't notice any leaks.

 

Nice! What kind of header did you install? Also.....in the future, they do sell a O2 sensor socket.
