I do believe i've settled on the Tbikes too. The sound from the vid file is as nice as any from what i can tell, and the no jetting feature is a HUGE bonus. Only thing stopping me is the fear that i'll buy them for my 05 speedy only to see them release a new version shortly after made especially for the 865 engine. I know some of you say they're BS'ing when they said they have one in the works. But i gotta think it makes sense that they would since it probably wouldn't take a lot of R&D to figure out how to change the baffling to optimize it for that engine. And i'm sure they know it would entice some buyers like myself who might go elsewhere due to the fact the current pipes are optimized for the 790.
And while on the subject, has anyone tried the Tbikes on a 05 speedy, and if so how did they fare as far as performance increase?
