wrap not a great idea if your pipes are nice, if not then i guess its an option. Can change the tune, allot more scavenging going on and could lien out the engine. As mentioned though more info, headers wrpped, pipe, both? any other mods, filters, re-jetted? When you say bounce around, 100rpm 500 rpm? does it do this when you are only in idle or while riding? I am surely not the pro in here but those that are will want to know in order to better help you. PS.....i have seen header pipe turn nice pipes into mush in less then 18 months....... just saying :-)
