I have a Webra 160 & an ES Carbon pipe. Pipe is 23 1/4" x 2" diameter. Baffel is 13 1/4"

What is the BALLPARK distance from the flange to the baffel? (Plus or minus 1 nano micron)

Check here:

There is no specific for the webra but you could use the OS 160 information as a reference to get in the ball park.

Good luck,

Vicente Bortone

25-1/4 inches inches straight line from glow plug to baffle should be a good starting place if memory serves me <g>

I think that was on a 16.5X12W on 15% Nitro Fuel
