WD40 is NOT a penitrating oil, or effective luberciant... U wouldnt have broken them off if you had done nothing to them.
PB is the best stuff out there for this type of work... High flashpoint, and low residue... Just do it...

Without disparaging PB, WD-40 IS a penetrating oil. I've used WD on everything from nuts and bolts around the house, to truck parts, to parts on F-4 fighter jets. I'm in no position to compare the penetrating, cleaning, or lubricating properties, or the flash points for that matter, of the two products, but I do know from over 25 years experience that WD-40 works quite well for its stated and intended purposes, which is a penetrating, cleaning, and lubricating petroleum product. Anyway, that's just my opinion.
the motor as a whole has smoothed out since installing the new exhaust. it seems to pull a little higher than it used to, and i have no problems spinning 35" tires in 1st. for me, yes it was worth it because my old exhaust was kinda sacked. my seat of my pants dyno feels like there is a little more grunt down low + the added smoothness...but i wouldn't consider it a huge jump in the power department.
