just got it today, i orederd the xtc one from CA (catless) and i noticed there is only one bung, where am i supposed to put my egt probe. what the hell i thought i ordered one with 2 bungs, but now looking on it i see none of the downpipes i looked at have 2 bungs, what should i do? there is only a bung for my o2 sensor, and i need one for a wideband or egt help!

 

you have to get one welded in, its not rocket science

 

go to a exhust shop they can weld one in for u

 

Well, since the second 02 sensor is now worthless, why not just screw your other thing in there?
It's really only used to watch/measure the efficiency of the cat. converter.

 

well the only thing is that the probe is small for the o2 sensor hole

 

because you still have a rear 02 sensor?

 

Just tune out the rear 02 sensor and use the one bung for the wideband. That's what i did.
