That whistle is extremely annoying.
I wonder if one of these would help rid you of that? http://www.ftediesel.com/store/pc/viewPrd.asp?idproduct=4&idcategory=7
I know they were made to eliminate in cab exhaust drone, but who knows?
That whistle is WITH the above item installed. lol. I can't imagine it straight piped.
To be fair. That vid was taken with high idle on. There is no whistle at regular idle.
