Alright, guys who have installed a test pipe, what is the socket size you used to get the bolts off the stock cat? im havingthe hardest time of my life right now :-/

 

lol... I had to use a 16MM and Pound the bolts on.. then just bought new bolts after I got it off.. and good luck getting the O2 Sensor off.. ur gunna need an impact gun mine came off with ease with 200 psi

 

you can't use a socket to get the o2 off without cutting the wires, i don't remember what size to use, but if you can find someone with an o2 sensor socket, that would be your best bet.

 

hes not talking about o2 socket man.. hes talking about the bolts!!!!!!!!!!!!!!!!!!!!!!!

 

i thought it was 17mm, thats what i used. and a breaker bar on my wrench. also... go to autozone or something similair and pick up a can of this stuff called PB Blaster. spray it on the bolts, wait 10 min, tap them a little, then reapply. 10 min later again, the bolts should come off with ease

 

^is right.. I have heard about that stuff... It Rules

 

17 mm will strip the friggen bolt.. i just took mine off 2 days ago when installing my turbo.. u have to pound a 16 mm on

 

see i cant get 16 or 17mm on, i have to use like 19 or 20 i think... does that sound right?

 

do you have the Lancer (R)etarded edt?? how do u use 19 or 20...??? does not seem right..

 

in reality you best bet is to get a striped bolt kit the like 50 bucks but worth every peny just put it on and when you cant budge it dont use wd 40 crap or a breaker bar just yous your legs put you fot on the wrench and push will come off no problem usely you legs are typicly 3 times stronger then you arms

 

im pretty sure his lancer is the same as ours, try and provide some help instead of negativaty. just find the wrench that fits best and use some PB Blaster to break the rust/metal bond if it wont come off.

 

thanks pickleknock...

no i believe i have the same on you do, but im not the smartest guy out there with tools, so ya instead of next time insulting someone keep your mouth shut or help out!

we dont need stupid comments like that making these boards negetive.

 

My favorite tool is my trigger start torch I tried every damned thing on the planet to get the O2 sensor off: sensor socket, PBlaster, 7/8" line wrench. . . no moving. Add a little heat (get the bung reddish- don't apply too much heat to the O2 sensor itself) use the 7/8" line wrench and PUSH! Using a little more of the Blaster won't hurt here either.
In terms of the bolts that hold the effin thing on- I can't remember but an impact wrench wil be invaluable, and for that ONE bolt, all of the above about the O2 sensor applies, too.

Good Luck ,dude!

 

ya heat will do it every time! the shop where i took it and they loosened the bolts for me they used a massive torch! but they got off the stripped bolts and o2 sensor in like 2 mins, haha.
