Had Vance & Hines slip-ons with Screamineagle tuner and hiflo filter and although sound was great it was just too loud riding around 4-6000 rpm.I was also getting alot of popping but when i went back stock what a difference. The bike is running much stronger and way better.Anyone know if this set up is okay or do i need to take it back to the dealer and get it re adjusted where the exaust is more restricted.
