I am/was a 4 wheeler man. Rode banshees. Toomey is "all that and a bag of chips" when it comes to Banshee exhaust. What is the "top dog" for the xr650l? (with no internal motor mods). Air, jetting, slide drillin', carb stuff, snorkle, smog, etc will be done. Just no cams, valves or pistons yet. Just some bolt on.
