I'm finally getting around to putting the VFRD WyLD (why is it called this?) header on my bike (along with a whole bunch of other stuff). While removing the stock pipe, two nuts came off the studs just fine. Six studs came out of the block (also, just fine). Didn't break any studs or strip any threads...until I tried to remove the nuts from the studs after they were out. Then I broke just one. But it made me realize, I'm not reusing these studs. So, now I'm trying to figure out what studs/nuts to buy.
Is stainless steel a better or worse material for header studs? Are the OEM studs as good as it gets?
I've searched the web for this, and answers vary. I called ARP. They said their stainless studs had the same tensile strength as their non-stainless. They also said they didn't make any to fit my (5th gen) bike. I've seen some cheap stainless steel studs on eBay. I'm not buying that crap. I'm looking for quality studs and nuts for strength, longevity, and ease of removal if needed in the future.
Also, the OEM studs I see available for 5th gens online say they are 6mm x 1.0 x 22mm. Measuring my studs, I get 6mm x 1.0 x 35ish mm (end to end). Are they measuring differently?
