I went ahead and wrapped my new Borla header. I also welded in another O2 sensor bung (for gauge) as well as the EGT bung. I wrapped it with 50% overlap and saturated it with three cans of the special high temp paint/sealer (black). I have had it on for over a week now and it is OK so far. I have heard stories of Borlas having very poor weld quaility and this may make it worse. I sure love having the EGT and air/fuel ratio gauge! Time will tell if it holds up very well...
