Hey guys, I bought my bike with some brand of oval slip ons, unsure of the brand since I dont see any stamps/markings on them. I am thinking of getting some screamin eagle slip ons instead, I have a stage 1 kit already done as well, will I need to get the bike remapped or a dyno run or anything like that? Im kind of under the impression that when you do a stage 1 kit you do it to that brand of exhaust, so if I change the exhaust it will throw everything off whack??? Thoughts??
