Update to that last message,   the combination resonator / muffler does have=
 some ceramic packing in the added section ahead of the muffler section  acc=
ording to a different source.  The muffler portion is the same as the muffle=
r only version.  Weight of the combination (XL version) is 10 lbs.  vs 6 for=
 the muffler only.   I'm going for the combo anyway.

hey call a resonator/muffler but it has no packing either.
