Hi All, Anyone know how long the header/pipe should be on the Webra 145 AeroX? The header looks short, ~5", and plan on running it with the ES 140D pipe. We are going to use the standard carb instead of the fancy needle carb. Anything else we should know about it? Thanks, Jason www.jasonshulman.com www.shulmanaviation.com www.composite-arf.com
