As a matter of principle, I use hi-temp anti-sieze compound on these kinds
of things.  It really makes life easier.  I first found out about the stuff
when replacing an oxygen sensor, and it really makes re-removal of exhaust
parts much easier.  Now I tell you, right?

The burbles are actually small backfires, vaguely audible with the stock
exhaust.  They are a factor of the shape of the camshafts and the spark
advance.  Sure does sound  . . . great!
