Topic: Is this exhuast special?

[Gorms]

I was told by someone that they were and when they pop up on ebay, they fetch a high price.  I cant find anything about them.  I'm mostly interested in getting them out of my shed but I would like to get a fair price for them if they are worth anything.

MAC made a 4/2 exhaust system like that r very similar to that with the turnout mufflers.  I have a set on a 350f , the hangers r factory welded on for the set on mine thou..

I've run across a few sets like that.  Nothing really special though.  What are they for?

[Gorms]

They came with my 550 but someone told me they were for a 500.  I like the look and may have used them but the flanges on the ends of the headers are so small that the collars hardly catch them.  I was going to weld on a lip but I just bought a MAC 4-1 instead.

Did they interfer with the center stand?

The MAC 4 into 2 set on my 72 350f doesnt affect the use & function of the cntr stand but the stand will hit & rub the bottom of mufflers when its raised. cured with a 1" pc of square tube welded to the bottom of the brake stop arm that works like a spacer / stop...

Its been a while but I believe so.  I do remember that the spacing for the exhaust ports is spot on.  They are different, no?

Take a look at your bike..do the pipes come STRAIGHT out? or are they ANGLED like the ones shown??
 I am not saying they did not fit in the ports but doubt they were flat against the sealing surface.

 Now look at the pipes shown in pic from the side, does there appear to be a 10 degree angle from the pipe were it exits head (up to first bend).. when you compare it to the lower (under the frame) section.
