Been trying to find some Threads on here about the Kerker / Supertrapp 2:1 Supermeg exhaust system. KERKER is Supertrapp from what I can tell. Some of my friends like their supertrapp disc system for tuning, but they are not as excited about their sound. They said when they went with the open end disc they got louder but lost performance. I see that the KERKER has a open baffle type system. I heard them on Youtube on twin cams, but not on EVO's and they seemed like a really deep throaty sound, and not as soft as the disc system. Anyone on here had any experience with the Kerker 2:1 SuperMeg on older EVO?? Looking for something to use if I take longer trips where I need bags. Current pipes in attachment I LOVE but not practical for long trips.
