I finished fabbing up the exhaust pipes that go from the headers to the mufflers. These pipes are 3 inches in diameter (same diameter as the header collectors). They reduce down to 2-1/2" right before the mufflers. The reason why they look different is, I had to rotate the passenger side muffler casing 90º, to make room for my ladder bar.
I will send these out to get powder coated in Grey Ice, so they match the headers. All that is left to make on the exhaust are the 2-1/2" tail pipes, and those should be pretty easy.
