For those who don't know, ThunderHeader exhaust is performance racing exhaust. This stuff ain't cheap. Had it on my 2005 Road King. My racing days are over now. Came with the bike when I purchased it 12 years ago. I got a soft spot for fishtails, so that's why I'm selling this exhaust system. Amazing deep sound !! I will surely miss that sound. ThunderCone, headpipes & heat shields. It's all there. Does NOT have O2 sensor bungs. My bike is carburated. $450 firm cash only.
