Stock Exhaust?
#4
with modification, anything is possible. Every exhaust company make sizes to fit any exhaust size (that i know of). Im almost sure its 2 1/2 or 2 3/4... when you get a chance crawl under your rear bumper with a ruler or measuring tape, hold it next to the pipe going from your engine to your muffler, and just eyeball so see what size it is.
