K&B .67 pipe length

[Ronnie Lerew]

I have a Miss Circus Circus hydro with a K&B .67 with MAC pipe. Never ran it before so would like a starter point of length. 50% nitro just looking for a ref. Dimension.

I'm assuming that is a Mac Exhaust 67 pipe

Not a MAC (Andy Brown) pipe

Mac Exhaust 11-3/4" from the center of cylinder to the widest point of pipe.

Start with a X455/3 or a X457/2

Rick,

That is correct a Mac exhaust pipe I think it is a #1365. Thank you very much for your help.

Is the Circus a Dumas hull?
