I can't see spending hundreds to quiet my Honda, but if you have a less expensive way, I am very interested -- thanks in advance!

Yeah, I'd have loved to have duplicated jauguston's genset quiet box but from scratch I figured I'd have been into at least $400 Cdn for materials alone, which I just couldn't justify. The biggest savings was achieved by utilizing an existing plastic storage box (about $12 @ Home Depot) in place of custom building one and forgoing the really expensive noise control barrier material, instead using some Reflectix that I happened to have on hand. The only part I did have some difficulty sourcing was some high heat insulation for the exhaust box but jauguston kindly sent me a small piece he had left over from his own project, otherwise most other materials I already had on hand in my workshop so overall cost was minimal. If there is any one improvement that I'm sure would make a noticeable difference it would be to use purpose designed noise control barrier inside the box instead of Reflectix but with West Marine here having to import it from the US and the exchange rate being as awful as it is I just can't justify the expense. With the genset running inside the box noise is greatly reduced but then placing the box in the back of my Avalanche with the cargo compartment closed up (but vented) really adds to the effect. I realize most don't tow with an Avalanche but anyone with a truck equipped with a hard tonneau cover could I'm sure achieve similar results. It's always easy to just throw $$$ at any project and make it successful but the real trick is achieving acceptable results while keeping the cost of the project within reason. ;)
