Well I took a close look at my NOS pipes today, they are 1-7/8" OD and 1-3/4" ID. They do not have slots where the tips go in,
so I don't know what the pipes are above. I bought these pipes in the late 80's and they had the part number on them that matched the 1969 Mopar parts catalog. The last pic is the reducer I had to use to make them work with the mufflers Accurate sent me. There has never been exhaust through these pipes, they were on my 69 383 GTS that burned in my garage, that is why they look bad. The tips and pipe hangars are NOS also...
