2-1 Siamese exhaust plunger/swingarm difference?

[Von datoh]

Yule tide blessings all,I recently purchased an a10 Siamese 2-1 exhaust (unknown model!) for my 650 a10 plunger project does anyone know if the swingarm model exhaust can fit the plunger frame I’m not worried about additional brackets to be made.Thanks in advance von.

Does yours have the correct plunger cylinder head?  I'm pretty sure the ports are the same as the swing arm head, many years ago I had a plunger A10 with a swing arm head and the exhaust fitted.  I think it will fit.

I have a set of later thick flange barrels and a later iron head possibly from a super flash ?

As far as I can see it only has to fit the head and clear inside the down tubes. Its may be a bit tight to install. My swing arm had 2:1 and its fiddly to get it in the ports and connected, it all has to be slid in at once.  The pipe should run close to the bottom tube and under the foot pedal.

Righto thanks for the advice hopefully will fit then with a bit of fudgery!.
