Topic: Are these CB550 headers?

[lordwhimsey]

The seller says they are but I don't recognise them.

They aren't like my stock '76 550F headers...

AFAIK, the stock 550F headers all curve to the right side of the oil filter housing, and they stack on top of each other at the collector in a square pattern rather than in-line like the one pictured.

and they're all bent to #$%* .... doesn't even look like they'll line up with the exhaust ports

[lordwhimsey]

I thought they looked a bit bent too! The seller describes their condition as a very precise 82/100.

[Gordon]

The #3 pipe may just be loose and not sitting at the correct angle because of it.  Different 4-4 exhaust work differently, but on some types a couple of the pipes are meant to be easily removed from the collector to facilitate the removal of the rest of the assembly from the bike.

If they are angled down to first bend and splayed.. they are 750 pipes..
 2nd time in a day I have mentioned this..

 far as I know 500 ports are all in a line 750 are not

I think you're right; looking at the parts fiche they look like CB750F2 headers. Pipes 1 and 3 are removeable.

Thanks guys, you've saved me some money

Although my header pipe quest continues!
