Yes, Johan has the rear O2s disabled and it throws no codes.

It will NOT pass a plug in emissions test like that.

Ok, thanks for that clarification. Now, what the heck is a O2s?! LOL!!

O2s is Oxygen sensors

Only thing I am wondering now is if there is a specific brand that is the best among the rest, or are the all pretty much the same?

They're all exactly the same. PowerBond makes them all in Australia and the companies sell them under their own branding.

Unless you're racing, it's not worth it. The gaskets are infamous for leaking and you'll find yourself every year or so replacing the gaskets

Sounds to me like he just didn't wanna do the job... I don't blame him, it's kind of a pain. lol Besides, 5.7s use a metal crush-type header gasket and aren't very prone to leaks.

I didn't write that, I'm all for headers. Thats what his exhaust guy said. I have no leaking problems with my headers. They were installed with Stage 8's with the heads off the truck to make sure they sealed properly.
