K model exhaust

[Scooter4]

Good evening,
does anyone have a picture or willing to take one of a K model exhaust system?  I have not found a picture that I can confirm is right.
thank you,

Exhaust is same as Model M, short style.

Thank you for the reply,
Please look at the attached image of the muffler I circled I think you are referring to.  If that is the correct one, I have more questions because I cant find K pictures showing enough to figure it out.

Does the flex tube go over the outside of the exhaust fitting (header) on the cylinder or does it have an adapter like the M model?

Does it have one or two outlets and are they in the same location as the M? 

I see a mount strap to hold the muffler up but do not know what it attaches to.

Please let me know.
Thank you,
Scooter

Part #4104 was a dress up sleeve that slides over the exhaust pipe.  It serves no purpose except to provide a little bling. 

The muffler slides into #1506, which is an aluminum casting that bolts to the head, same as a Model M. Simplex changed from a slip-in to a slide-over on that pipe sometime in the later 1950's, as the earlier style always leaks a little oily residue. Muffler #1504, is the correct short style for your bike. The long dual exhaust was not available until after 1954, I believe.

There is no strap for the short muffler.  There is a 1/4-20 bolt with a turned down tip that gets tapped into the aluminum manifold.  This is drilled in place when you install the muffler.  On the exhaust pipe there is a hole, which gets bolted to the front engine mount bolt.

Thank you very much for that picture.  I would have never figured that one out.
The piece in the image I circled I thought was a mount strap is the exhaust pipe.
It appears the exhaust pipe is just long enough to get the hole in it to mount under engine.

This will be much easier to make than the one I did for my M.

Thank you,

The exhaust tip is angle cut and flattened slightly to mount under the motor plate.

Here is a picture of one of Wayne's reproduction mufflers that I had Hi-Temp powder coated.

Those pictures are perfect.
I may start making one this weekend unless it gets much colder.  I already have the tube and two muffler end disc's I copied from my M.
Thanks a buch,

Post a pic or two when you're done .

The one I made and am using is a little different than Wayne's or OEM .

That is pretty cool looking.  Creative end caps.

Thanks .
It's all copper , but for the 1/4" aluminum end caps and some 1/4-20 threaded rod to hold them on .

Good evening,
I am finally setting up to make this muffler.  I had to make some frame repairs before I could mount the engine.
I forgot to ask what diameter the inlet and outlet tubes are, the outlet tube in the pictures looks smaller than the inlet.
Please let me know.
Thank you,
