I am finally getting ready to buy a D2 for our project and have a few more questions from those using them, I know many use the D4 but suspect there would enough similarities.
I have heard they can make some noise, I dont need silence at night but would like to plan as best as possible to reduce noise.
Is any one using a muffler on the exhaust?
How about insulation around the exhaust, it seems Espar makes some "sock" type material, limited info but it appears to be minimal and wondering if some exhaust wrap would be worthwhile.
Combustion intake, I can easily run this out the bulkhead (~3'), any value in that?
Also they make a muffler for the intake, anyone use one?
And last, what about the fuel metering pump, I may be able to install that in the cockpit, near the fuel tank, have heard they are noisy as well..
Well almost last what do you do with the drain line off the elbow?
