Correct Part Number for 1972 FLH Mufflers
I am trying to do a spot on correct restoration of a 1972 FLH Shovelhead and I can't tell if the correct muffler part number is 65244-70A or 65242-70B.
Do I need an A and a B for left and right? Which number is correct?
I have also heard that the B might be an ultra quiet version?
Any insights people can provide would be hugely helpful and much appreciated.

Part number not visible on the other side just HD MOCO Inc. I seriously doubt there's a different part number as there doesn't appear to be a reason for it. Mufflers are attached via round hangers that slide onto the mufflers so I wouldn't think there is a right or left. Looked in my parts book and confirmed numbers Panz came up with. IMO the B is the extra quiet and you could use either the 65242-70 or the 65244-70 and decide whether you want the standard or extra quiet.

Hi guys
appreciate this is a really old thread...
I stumbled across it the other day searching for similar info and thought others may be interested in what I have
I have a 1972 FLH with a build date of September 1971
it had some aftermarket pipes on it, but came with some original exhaust parts including mufflers
One muffler is a 65244-70B and has an outlet size of 1inch
Other is a 65244-70A and has an outlet size of 1 3/4 inch
They are the same length and have the same diameter inlet I have made the assumption B is for the right side and A is for the left side
I went with a single system and fitted the B muffler and yes, it's quiet
I couldn't find these numbers in the parts book either but they do look like the mufflers in the book
Cheers
