Help, Can't take off stock H-pipe

[kylebgt]

I was able to get the dreaded header bolts off easily, what I am having troubles with is the o2 sensors. I was able to get 1 of the rear o2 sensors off but the front ones will not budge. I am using a 20 or 22mm open ended wrench. I have sprayed the **** out of them and given it all my strength and nothing. Any recommendations/opinions are appreciated!! lets get my x-pipe on today

Did you spray them and let them sit for a while? Are you using PB Blaster?

I just sprayed some WD40 on them, let it sit for about 5 mins and they came off pretty easy.

be carfull using am opened end wrench, you may strip them

mine where on so tight i had to use a wrench for brake lines

I have always changed them when the exhaust was hot after letting them soak overnight in PB Blaster.

i always used a O2 sensor socket and never had a problem.

If the pipe is off the car go get the o2 socket from a parts store. If its not off yet, unclip the o2s from the harness, drop the pipe out, then go get the 02 socket. Right tools will make it soooo much easier.

take that wrench, with the pipe off the car and give them a good forcefull blow with a hammer.. thats how i broke my friend chads loose

eat your veggies man

broke mine loose with a Vise Grip, it came out relatively easy. the hardest part for me was trying to unplug the damn harness!

I'd add, spraying and letting soak in some PB type stuff for a while. Had to use a rubber hammer to break one of mine loose. I know what you mean!!

I unplugged em, then dropped the pipe and then took them out. Alot easier on the floor of the garage.
