Tuned Pipe Identities
« on: January 27, 2011, 06:53:33 PM »
Hi Randy and all,
   I have a couple of tuned pipes that I want to confirm their identity and useage.
I've attached some pictures.  The longer one is meant for the PA 65. The shorter
one appears identical but has a shorter pipe before reaching the first cone.  Is the
shorter one also for use with a PA 65, or is it for what engine?  The longer one is
almost 19 inches long overall, with the yellow mark at ~14 7/8".  The shorter is about
16 3/8" overall, with the yellow line at ~12 1/8".  Neither appears to be cut or modified.
Inlet diameter is ~3/4", outlet is ~1/2" (for both pipes).

Hi Stan

Those are both the old Diamond back 61 65 pipes, You can use them on both motors  61 and 65. The important dimension is the distance from the glow plug of the motor to the first reflective surface ( first baffle)
Make sure they have the alum inserts in the front of the pipe

Regards
Randy

Thanks Randy. Nicely made tuned pipes.   
The inserts are intact.
