i have been looking a bub 7 exhaust and wondering why is the crossover pipe kit like half the price.i know the kit with no crossover looks better but is there any difference when it comes to power or performance.thanks

 

I'm not sure what year of bike you have , but the i have is the 09 with the stock 2 into 1 into 2. I installed the bub 7s with the pcv and am very happy with the performance from stock muffles. Not crazy load but when you pull up from behind your noticed. Nice rumble also.

 

I have a 2010 and installed Bub 7 x-over with a p/c v. The cross over will give you much better low end torque than the dual. All depends on what you want!
