Inside diameter of the original tip is 1.62, OD is 1-7/8.

Original Tailpipe is 2.25 up over the axle then pieced to 1-7/8 down to the tip. Most repop tailpipes are 2.25 all the way. I may be incorrect with the actual sizes and the police will correct me for sure. The original tailpipes are 2 piece welded though and I still have the original 383 pipes I saved. So you can see the restriction of the originals.
