O/R H pipe install questions...

[powerfreak]

I pulled out my stock H pipe (holy crap, that's a lot of cats)...going to install the H tomorrow. Couple of Q's....does anyone know what size are the studs/nuts on the drivers side that connect the H pipe to the ex manifolds? I got them off, but they're hammered, need to get new ones.

ALSO, I'm going to be ordering an XCAL tuner tomorrow, can I just leave off the o2 sensors (and plug the holes) and order the tune to omit them? Just wondering because that front pass side sensor is a PIA. :dunno:

thanks guys

Im not sure of the bolt size, however the REAR o2 sensors are the ones that can be turned off...No tune will cut off the front ones.

thanks...figures the fronts are the PIA. So I guess I should just plug them because I dont have MIL elims, so I'm going to get them turned off with the tune anyway.
