Earlier comin home from work I saw another ss/sc. IDK what all was done to I figure it didnt have cats or mufflers cause it was a killer on the ears... He pulled up beside and kinda got on it in second, it was screaming, and then when he shifted. It popped a couple times really loud then a big puff of fire came out. IDK...It was awesome though... What do you think this guy had done?
