Just like the title says. I'm thinking about buying one for around 200 bux, used. That's the full exhaust -- header, stinger, silencer, flange, springs, etc. How does pro circuit rate against LRD, Shearer, F7, etc. I do mostly trail riding and hill climbing. My buddy puts nothing but pro circuit on his banshees, but I don't know if theyre just as good for the blaster.
