It's loud and makes all sorts of whooshing and whishing noises whether you're up or down shifting going easy or WOT. I'm loving it!
OK small update: Today I got some racing Tow Hooks in the mail (off eBay). They had anodised red ones but I'm not one for being too flashy and I've read that the red anodised ones fade pink so I went for some black ones.
596g for the pair.
Rear (I drilled a hole out of the plastic tow hook cover to make it look a little cleaner).
Front hook. Unfortunately the hook doesn't fit through the honeycomb holes already in the front fog cover (silly of VW as you'd have to remove the fog cover to get the stock tow hook in there too) so I had to dremel out some plastic to get it to fit.
