I've got an original JAWS. At 38 oz of Ti, he should have name it the Whale! It's a nice can. Just a TAD on the heavy side. Accurate, with a repeatable POI shift.
In all my time of shooting with and around mufflers, I've never really heard a big difference. Try and find one around $1K. I have more Ti in my can which make me feel "better" about spending $2K on it...
