John,

Me thinks your project will have the correct bottom line. You have been willing to put it all out there for all to see and follow the trial and error process. Pehaps soon you will have a great answer concerning to more or not to move the muffler. My trial required too much length in the pipe to relocate the muffler. The box was used in a Factory Genset Compartment. The compartment was on the passenger side, requiring a double back. 36" total piping, giving off lot's of heat. Nother thing. I used water/gas 3/4" pipe with 90 degree L's. Creating to much back pressure. Causing ther engine to over heat. Your idea should be a winner. Please give us more info' on your progress in sound lowering. Many are looking for some answers to cool and cut the noise. Do you think more air movement might be necessary?

Floyd,
In my application, it looks like I can have a radiused bend coming right out of the exhaust flange and then straight down and out of the genset enclosure ... probably no more than 15" of header in the enclosure. The top of the enclosure has a 8"/500 cfm fan that cools very well right now. I'm hoping that with reducing the heat burden from the exhaust and using some baffling, it will remain sufficient. However, if necessary, I think a 10" fan with 1500 cfm is available. It'll take some monitoring of the enclosure's temp and the CHT to be sure ventilation is adequate. (I have the genhead's temp on a gauge already.)

It'll be this winter before much data is forthcoming, probably somewhere between 9,000 and 10,000 posts on this thread!:B

Regards,
John
