Default Muffler Pipe Size....?

I have a 1981 Coupe and I was wondering if anyone knew the correct muffler pipe size? It looks like my pipe is 2 1/2 inches all the way from the exhaust manifold to the muffler. I don't know if this is the original size or if it was changed to this size by previous owners. Thanks in advance for any help.

Hi Richie,

Sorry, don't know the pipe size. I'd say 2 1/2 sounds right though.

Hope all else is going well.

Joe..

The front y-pipes are 2 inch, but the rest of the system was 2 1/2 inches.
