Have set of screaming eagle slip ons that came with bike when purchased . My question is that I want to take the stock pipes off and put on the sceaming eagles do i need to put it on the dyno at the local stealer or not. Some buds of mine say it does'nt need to be dynoed some say it does. Stock pipes just don't have the sound that i'm looking for. Bike is 09 heritage with 4000 km on it. Any feedback greatly appreciately. Thanks
