I purchased the Two Brothers aluminum black series slip-on and P1X quiet core. After I got it installed the sound was great, but it popped and sputtered a bit on decel and power could be a little better. I ordered up the Dynojet PC 5 and got it installed, and loaded the map for the Two Brothers slip-on exhaust and stock filter. Wow runs great now, no popping on decel(only slightly once in a great while), and power and acceleration is strong 4,500 rpm's and up. I love the sound, not too loud but roars quite nicely when you get on it. Very happy with this set-up, worth the time and effort to install it.
