When installing New Exhaust system on 63 Avanti, is it required to install JB Weld product on the ends of the pipes before installing into muffler and other pipes to prevent from Exhaust  leeks ?

Not if you have good clamps and the pipe fit well.  If not, don't mess with JB weld, there is a muffler pipe sealer made by permatex that Oreilly auto parts sells, which would be much easier to use.  (no mixing needed)
