PM'd ya. A couple of questions that I'm pretty sure you'll get alot, but shouldn't get anyone in trouble (if not, my bad):
-Are these set up like the Vishnu or TurboXS stages, such that once I buy into stage 1, stage 2 is cheaper?
-I've already got the Prodrive muffler, does that change the price as well? I could always sell the new muffler if not.
As a general point, I've been mighty impressed with the couple of Prodrive upgrades I have so far. I wouldn't have any problem at all buying one of these packs even if they were reasonably spendy.
