Lol I'm glad I'm not the only one hearing dumb **** every time I go to the gas station today this dude with a 10' ss camaro compliments my exhaust and tells me nice ls1 so I tell him no these only had ls4's he says straight up dude gm never made a ls4 they only mad ls5 and ls1 motors I couldn't tell if he was serious but he explained that his LS5 motor makes 530hp stock and his exhaust added another 100 but yet this douchebag is filling up with 87 octane. After that I had to stop pumping and leave because I felt a annurism coming
