Stock Muffler

Anyone have a pic of a stock 7.3 muffler?
I bought my F350 used and it looks like the exhaust may have been changed but I can't tell.

It's oval and uses all the factory mounts, but the pipe looks big.
From what I can tell, it also changes diameter near the front.
The pipe coming from the turbo is one size(may be 3"), down to where it curves and starts to run horizontal. At that joint it gets larger by at least 1/2" to 1" in diameter.

From there it runs back about 3 or 3.5 feet to a really short section about 18" long, then into the oval muffler. From the muffler its all one size back to the tail pipe. It is rusting a little but is heavy gage metal tubing. The Truck only had 39k when I bought it, so it must be fairly new if not stock.

Thanks

easiest way to check is to measure the diameter of the tial pipe. stock is 3.5 inch and non stock will be bigger. and i think stock mufflers are round but not sure.
