Need specifics. Which engine do you have ? Do you want the factory specs that came originally on the car when new?

I know I'm right....
if you got a slant, it necks down to almost 1.5 at the cheap weld in the headpipe. Ma designed in torque in their exhaust systems, not total power, so its usually more narrow than you would imagine.

i have a 225 /6 in it, stock. hopefully swapping to a 360 soon
The factory pipe size for the 225 /6 is: 1-3/4" headpipe , 1-7/8" tailpipe.
For 360 duals: 2" flange pipes, 2-1/4" intermediate pipes , 2-1/4" tailpipes.
