    Stainless exhaust studs replacing bolts

    OK. I think I've read the pertinent 2+ pages of threads dealing with exhaust studs but still need some guidance. I'm looking at purchasing this stainless set from amazon. Any objections?

    Also I've read conflicting posts on the use of either thread-locker blue/red + ant-seize on the nuts. Or Use anti-seize on the studs and anti-seize on the nuts? There seems to be at least 2 very different schools of thought on this. Maybe there's no right or wrong answer? As long as the stainless bolts have something on them to help avoid a galvanic reaction between steel and aluminum? Or is that not possible with stainless? Or should I buy something other than stainless? If so, what? Not sure what to do.

    Stainless studs are good. Use thread lock on the studs in the head, you dont want them unscrewing when undoing the nuts, other wise it defeats the object of fitting studs in the first place. Anti sieze on the nuts.

          I am concerned about fitting the beefy, finned flanges over the studs where they are close to the frame. I'll do some test fitting before I permanently install the studs to see if it's going to be a problem.

            Yes, I went back to bolts but at that time I had a Yosh pipe fitted that meant I had to remove the pipe to change oil...

              Do you have steel or aluminum flanges? The aluminum are beefier and may have a minor clearance issue that should be easily fixed with a bit of trimming. IIRC I think it's the outside two that are a bit tight against the frame tube. The steel ones are smaller and easily fit.

                I believe the flanges are aluminum. They have teeth or fins that are longer on one side and shorter on the other. Can't remember if the big teeth go up or down, probably up. Anyway, looks like it's probably gonna be tight to get these big flanges over the studs near the frame members.
