yes, i said tinny (it's not a typo) with two n's. not tiny as in small. tinny as in sounding like timmy only with an n's instead of m's. i don't know if you guys know what i'm sayin, but i don't really know how else to describe it. anyway, i'm not always hearing it - it usually just happens either during hard acceleration or right after i let off the gas after hard acceleration and it's coming from behind me so my best guess is something with the exhaust. and it doesn't always happen either - usually only about 1/3 of the time i floor it, and sometimes it happens even when i'm just driving normally. the sound only lasts for about 5 seconds long max, too. so what in god's name is it??? it's kinda buggin me. oh, and i just got the car 2 days ago so if something caused it i dont know about it. the exhaust is stock. thanks in advance.
