    I'm replacing the single exhaust on my '65 Chrysler, and am not sure 100% about the placement of the tailpipe.

    I believe it is supposed to run inboard of the frame rail but not sure how close horizontally or vertically to the rail.

    Anyone have dimensions or photos of a stock setup in that area?

    Thanks,
    Dan

    Dan I have a few pics.
    Let me dig them out of my archives.
    The tailpipe runs between the gas tank and frame rail slightly lower than the frame rail.
    Stock tailpipes end before the bumper and have a baloney sliced tip.
    Btw, you still have the blue Dart? Lol!

    No, the Dart lasted till the spring of 2014. It just got too rusty & needed significant engine work so got parted out that summer.

    After 7 years I figured out I don't have the time/energy/budget to keep more than one old car together.

    The current daily is a Buick from Alabama. 18 years old & no rust! :)

    In general, the pipe is closer to the frame rail than to the fuel tank. With the normal C-body muffler, seems line the rear pipe is pretty much on the same straight line out of the muffler after it goes over the rear axle? Consider, too, that the L-shaped rear hanger is about 2.5-2.75" in its horizontal dimension.

    Just some thoughts,

    When I used to do exhaust work in the 70s, a good rule of thumb is... the width of your thumb between any metal as a minimum.

    Thanks guys.

    I got a complete setup from Waldron's and it seems to fit quite well. Problem is my car has a trailer hitch, and it is pretty much exactly where the pipe is supposed to run.

    I'm thinking tweaking it down and over (under the frame rail) is going to be easier than up and through the hitch frame, but we will see.
