factory exhaust size
i bought my ex 4th hand and its for the most part stock. but i was under it for the first time and the exhaust looks a bit large and aftermarket. i measured the pipe and its a 4". i cant find any markings on the muffler though so i assume its on top. i even tried to google the stock exhaust size and came up empty. anyone know what size pipe the stock truck had and about how big the stock muffler is? i wanted a MBRP 4" but if i have one already or one like it then it saves me money and ill just buy a TS chip. thanks guys.
