What does the exit on the manifold pipe measure? I am showing just a hair over 1 3/4, but I just want to make sure. If you go to the Walker muffler web site they have a pretty decent search for mufflers, it's just a matter of having the right offsets. The original tail pipe appears to be smaller than 1 3/4, but I plan on having a new one made out of 1 3/4 material anyways.
