anyone know the size of the piping on the skunk2 exhaust???

 

Did I misread your sig? If you have one, you can just measure it. You'll get only the outside diameter but that's spec other exhaust makers use to describe their pipe sizes. If you don't have a caliper, wrap string around the pipe to get the circumference, divide that by 3.14 to get the outside diameter.

 

2.5

 

lol so true
