first i got a dynomaxx cat back system with headers...thats just the exhaust mods.....and i can get leaded race gas at the pump in elkhart lake by Road America in wisconsin....(the kart racing track) i can get it at the pump at the gas station off of hwy j.....
its power 110 leaded race gas....i put that in my race quad...
and in my count ther are no smog checks.....no emmision tests....and the cops are very lienient about the exhaust noise so that aint a problem for me
