Shit, I hope I didn't damage the sensor transferring it to the new cat, didn't have a proper socket so I just used pliers

>>17579082
How about a 7/8 wrench?

>>17579371
I just remember I didn't have a wrench big enough for it. I had a socket, but obviously that wouldn't work because of the cable at the end.

When we do cats we highly recommend new O2 sensors with it.
Unless they're relatively new

>>17579060
It's coming back don't worry, just keep that cat for a little

>>17579060
>Not just removing the cat and tuning it out
Such a pleb

>>17580426
Well you're just a fucking Jew aren't you?

What's wrong, people saving money unbearable for you?

>>17580439
Nope just dont want faggots like you coming into my shop 6 month later "hurr durr my light came back on, you didn't install the cat right"
No you idiot the O2 sensor took a shit

>>17580455
Or maybe you should go back to monkey wrench school so you don't fuck people over twice? Yeah definitely

>>17580426
Well, it's like a $40 part, and luckily, unlike the $550 cat, I think I can change it without taking apart half the exhaust system

>>17580476
You are wrong my man

>>17580476
And that's great, go ahead and do that, I wont lose sleep over it. And that makes you more mechanically skilled than 95% of the people we deal with.

>>17580459
There are tons of things in all fields that you just replace while doing a bigger job.
It's like doing the throw out bearing when doing the clutch.

Or like putting my cock in your moms mouth, goes hand in hand
