I eas agreeing to that my turbo whistles like hell, it whistles at idle, and at 1500 rpm it sounds like a jet airplane and just gets more from there:sly

Thats one bad ass bug.

I get turbo noise with mine too but a LOT more under the hood if the plastic air inlet to the filter box is removed. Sounded better without the muffler though.

I've got a 3" downpipe off the factory elbow into a 4" open exhaust. It whistles plenty. Way, way more than my 6.0 does. Sounds good too.

And on the topic of whistling VW's. In Brazil they have VW semis'. I heard on a few occasions one of them being shifted while pulling a heavy load. Damn! The whistle those things create was awesome.

Thouse VGTs make them sing. I've heard some 7.3PSDs where the owner left the wastegate line off not plugged just off and they whistle like crazy could hear the whistle miles away but that was more of a massive boost leak causing the whistle but it sounded cool.
