Most of that price is the added tips so you won't melt your tire, ceramic coating, custom J-pipe, etc. I could go buy the same muffler for like $80, but I couldn't put the shit together myself :rolf:
Assclapper or not, that Magnaflow is good for a 10% increase with a tune. I've seen a dyno chart of an XB12 going from 89whp/90lb ft to 98whp/99lb ft with the same setup.
At least with a Buell, the bike will be long gone by the time it hits 3rd gear.... Unlike most HD's that still wouldn't have passed where you're standing :rolf:
If you really wanna hear an assclapper on a Buell, look up any of the modded stock pipes, or the D&D pipe.... That fucker is obnoxiously loud
