how do you know the size of your exhaust... 2"? 2 1/2"?
if i ask my bro he'll probably slap me... this way the worse that can happen to me is a few "lol's" and namecallings!

measure across the pipe to tell...

or if you can get a clear reading that way you could get a piece of string and wrap it one time around the outside of the pipe, measure the length of the string and divide that by 3.1415
