Thanks in advance!

Pretty sure I have a stock exhaust all the way. I think it's all 2" pipe. Just so happens that I used a 1971 250ci to replace my 230ci in my 1965 C10. Here are pics. Everything bolted up to the factory locations. The muffler shop guy had a book that told him where to make all the bends and he didn't even have the truck there in the shop. I installed it myself.
