I think I read that correctly... it's essentially saying that with the new (quieter) muffler, they got less fuel consumption and higher thermal efficiency... is that correct?

So what does that say about flow? Was the new muffler quieter with higher flow?

Also, back on the original tract of the discussion, SuperTrapp mufflers claim increased flow and HP across the board... which should mean higher efficiency due to lowered pumping losses, regardless of throttle position or RPM.

How does that conclude to "adding a muffler can't increase your fuel economy"?
