exhaust size

what size piping should i go with on my exhaust any input is great thanks its a non turbo rs by the way

I believe the stock exhaust is already 2 1/4 or 2.5 inches already. I'm planning on going with a 3" on my 01 GT

the stock size is 2.25". if you have no plans in the near future to go FI, then just get a 2.5" exhaust.

if you are not planning on going FI, the 3" exhaust will hurt your car's performance
