Topic: Does anybody know what these mufflers are?

[JBMorse]

I posted this on a couple of other forums, but wanted to show it to you guys too.  For my upcoming scrambler project.
These mufflers are listed as being for the CB350, and I'm sure they'd work on one.  Obviously they're not original styled CB350 mufflers, but I like them a lot and may buy a set.

So what are they?  They look like something a British twin would use, but the diameter may be wrong for that.  I thought they were just some EMGO knockoffs but I can't find them in any EMGO catalog. 
I'd like to find out more about them before ordering because this company is in Thailand and doesn't offer much info on them.  If I can find them sold closer by I can get a closer look and save on shipping I think.
Specifically I'd like to know how loud they are, approximate weight, whether the baffles come out for possible repacking, and what the quality is like.   So if you all have seen ones like these for sale somewhere else, please chime in!  They may just be a no name Taiwanese knockoff, but if they're available elsewhere I'd like to know.
These would be for a CL350 project I'm contemplating that would have a high-mount exhaust on each side, like some Triumph twins or 60s Japanese scramblers like the Suzuki Hustler.



That Triumph is a 2-1 but it's sort of the look I'm going for.
So far my plan is to buy some mandrel bends and weld them together as neatly as possible to create the headers I need, and then get them ceramic coated to be nice and shiny.  I'm hoping for a prettier, lighter, better performing system for my project. 
Any insight would be great!
Thanks!

They look similar to the aftermarket units offered for the XS650 Yamaha.  Take a look at the CB-CL450 'D' kit offered by Honda to convert existing black bombers at the dealers to scramblers.

They look similar to the earlier Triumph Daytona mufflers (1970-75ish). You could be right about the diameter sizing, you would nned to do some investigating. Cheers Brett

oldscrambler,
You're right, Mikesxs does have a muffler that is similar in style.  I hadn't noticed it before.  It's their "old Brit style muffler with long inlet."  It does have a longer inlet and shorter muffler section than the ones I posted.  Still, maybe that would be a better route to go anyway.  I'd feel better about buying from a renowned US company than a random ebay supplier in Taiwan.  With shipping, the price would be reasonably close too.

I have a couple of pictures of the CB450 D in my collection of inspiration pics from the web.  Overall, this scrambler is going to take a few styling cues from 60s Hondas.  In fact, I just ordered a CB77 speedometer from ebay that should arrive soon!  I'm planning on mounting that inside a longer headlight bucket from roc city cafe.  That way I don't have to give up my tach or speedo, I can have both! I'll start a build thread soon.

Brett, I can't seem to find any pictures of that specific Triumph, but I'll keep my eyes open.  Sometimes I can find used Triumph mufflers pretty cheap as well, so that's another possibility.
