1978 Honda CB400 Hawk muffler part numbers

[John Firek]

Hi all! Been racking my brain to find the correct mufflers for my project.
The bike did not come with mufflers. So, I have no idea which to buy. I purchased a few and they do not look correct. The current model I have is #HM443-k. They look too long.

Please help!
TIA

You did not specify complete model.
This is from 78 CB400T2

The part code is 413 but since it fits all the 1978-79 models it would likely say 413-417. 417 is the A model part code.
The one in the picture would be correct, fiche shows 4 similar but different end codes, 003/013/023/027
