The other pair I had, the innards sound as you have sdiscribed. One side you could look almost to the end and the other when looking in from the engine side was only a few inches. You can do some research around here and find the "good" part numbers. I picked up a pair off a 2012 Street Glide I think. Slash cut rears. I know no cats because after like 08 or 09 there EPa figured no one was leaving factory muffs on and there by defeating the catalitic converter.
OK did a little research for ya.
