    1969 427/400 Side Exhaust 2 1/2 "

    I just received my side exhaust pipes from Paragon this morning. They start out as 2 1/2" pipes but then reduce to 2" right away. Is this the way the originals were or were they 2 1/2" all the way through? Also there is a short sleeve that holds the donut ring. This is not what I was expecting to show up after a long time of waiting to get to this point.

    That's how the originals were configured. All 1969 Corvette applications, base engine to ZL-1 and undercar or side exhaust, used 2" exhaust.

    The extension ("short sleeve") you are referring to was used on all original exhaust systems. For 1969 small blocks, the extension was 2"; for 1969 big blocks it was 2-1/2".

      Joe,

      Thank you very much. I'll be putting the pipes on later today. I just have the chassis complete with the engine in it but I plan on starting it up in the near future.
