Stock Exhaust Size.

What is the size of the piping on a stock s13 exhaust system? Couldn’t find it anywhere,

2 1/4

stock piping is 2 1/4 inch? no way it looks much smaller than that.

maybe before all the bending that leaves it looking like a grimey pretzel…

It should be 2" in diameter in stock form if i’m not mistaken.

i measured my stock one a couple years ago and it was slightly under 2in

Yea that sounds alittle more like. My 2 1/2 inch dwarfs the stock piping before it.

The piping is 2" and drops down to as small as 1.6" through the bends.

Thanks guys.
