I just needed a quick size on the stock exhaust system piping. I have a fifth gen hatchback, im guessing its 2.5 but im not really sure. I can't imagine it could be smaller then 2". I'm trying to decide how important it's going to be to upgrade the exhaust system once I bolt on my turbo. Thanks,

I think it changes from model to model. I think the si is
2.25"

Stock EG piping for CX/DX/VX/LX is 1.5" I believe
For EX/Si I believe it's 1.75"

1.75 sounds right.. There is no freaking way stock has 2.25
