Why don't you just go measure it. It's pretty easy if you have a set of calipers.

If not just use the string trick. Wrap a piece of string around the exhaust pipe. mark where it comes around and measure that.

Now you have your circumference.

d = ( sqrt( C / pie ) ) * 2

there you go that's the ouside diameter of the piping.

I would do if for you but I already changed my exhaust. Maybe somebody has a set answer ?

Anyways if your getting a custom exhaust just ask the shop.
