Well I think if you were on an real tight budget and knew you might never get a slip-on or complete exhaust that might change your exhaust note a bit. I doubt it would give you much performance gain but hey it's something different and to each there own.
Can someone tell me if the stock KFX silencer has baffles like the LTR or if its a straight through core.
If it's a straight through core, that end cap along with no airbox lid and a tuner will be an awesome budget setup. If its got baffles like the LTR you would be better off saving your money for a slip-on.
