Did HPI close down? I have not heard about these mufflers in awhile. I have HPIs and they just barely make me legal with twin stock HP500s, but no loss of power.

Just put 2 pr. of the GGB's on our Fountain. Had Stellings with no mufflers on 950 S/C's, and boy, were they loud. Now, it's much more quiet, yet it still has that good sound without the bite of an open header.
BTW, No power loss that I can see.
