I never hear any talk or see pictures of it installed. Is it louder than the single can set-up? The propoganda from Aprilia says 'race' only. Is the dual can system too loud for the street? the dyno charts in the 2002 Aprilia catalog show power gains everwhere. the single can set up is $599 USD and the Dual is $899 USD, both come with a chip.
I am getting my bike this week and it is easier to order stuff when you buy it, since you can roll it into the loan.
