    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

ID this 4 into 1 pipe for me?

Looks exactly like a J & R system I had on a Honda 500/4, way back when.
 
On Steve's bike, I meant to say series 7 Yosh which a friends older brother had back in the day.
His was RR chrome style running up the middle of the oil pan also having a short upswept silencer ending a fair bit before the axle bolt.
I guess similar to Wes Cooley's old race bike, but his was black.
It looked so clean an tidy on a metallic silver 80 1100E. Used to "goon out" on it whenever I heard or saw it.
The collector looked somewhat similar in shape to Steve's, but much more upswept.
The baffle on the end of Steve's is the only thing that looks similar to the Series I Yosh I have.
Never heard of Marshall, but that photo with the individual pipes look like the same bends on the header.
 
Looks like what you were describing:

Cool to get one for $180 these days ha!
Where would one find dads vintage ads, if not looking specifically?
Wish Yosh would be willing to make some of these again, seems they have the tooling, and a fair number of folks around the world would probably buy them.
Any pipe passing the axle or having a down turn spigot doesn't look period correct on a near 40 year old MC.
Guess emissions and DB might kill that wish.

You can't really tell from the pictures that I posted of my bike, but I kill both of those items. Actually, the end of the muffler is ahead of the axle, but it's right under the saddle bag, so I added an extension to get it to the rear of the bag. Yep, it turns down, too. :-\\\

I'm not shooting for "period correct" with my bike. There are SO many things about it that leave the purists scratching their heads because it looks right, but not quite. Some just can't tell, which is what I like. :encouragement:

I think it is a Jama
Got the same on my 550E

Ahhh.... is that inscription on the muffler located on the back side? It's now in an unheated garage at my friend's house, so I'm not able to check it out directly...
The Marshall exhaust (made by JAMA) had an indent in the muffler megaphone for the Marshall logo, so I discounted the Marshall/Jama idea.... the front of your Jama looks strikingly similar though!

Can you perhaps include a photo of the baffle?, and the entire megaphone/Muffler as installed on bike from side view???

THANKS for chiming in!
