you can either
a.) measure the width (diameter)
b.) measure the circumference (distance around the piece of pipe), divide by pi (approximately 3.14), then find the square
root of your answer - double that
<ex> if cir. = 7.065" (just over 7 inches), then dia. = 3"
because 7.065/3.14 = 2.25
square root of 2.25 = 1.5
1.5 X 2 = 3
c.) let an exhaust guy take a look at it and tell you
