s13 exhaust piping?

[miracleboi123]

does anyone know the oem exhausts pipe size?

i got a magnaflow muffler today, and its a 2.25 inlet to 4.0 tip, but i am just wondering cause i want to upgrade all the piping + to a higher flowing cat, but is the oem exhuast size already 2.25? cos i might as wel just use the old piping then, if it wont make much difference.

yeah... hmmm I believe its 2.5 actually. Been a while since i last had to deal with that, but yeah I pretty sure it is.

2.25 is bigger than stock piping on 240's. The oem piping is no bigger than 2 inches. It's pretty pathetic looking.

+1 I remember doing the SR swap and just seeing how small the exhaust piping is!!
