Akrapovic will launch a series for the MK7 early next year...http://www.akrapovic.com/en/Automotive/products/Pages/ProductList.aspx?BrandId=8c20bbe0-cef6-4078-b78b-38298a2aa08b&DisplayName=Volkswagen Golf+(VI)+GTII have used this firms exhausts and rate them highly, they're beautifully made and sound great. The resale value is also good. There's plenty of youtube vids of the mk6 with Akrapovic...
Like these? http://shop.rossiters.co.uk/volkswagen-golf-mk6-gti-62-c.aspI think the best additon Ive seen to the GTI is the PP option, sounds like a proper bargain. Shame there's no similar offering for the GTD. My mk6 GTD could be found wanting entrying corners, its way to vague for my liking.Akrapovic offer a system for the MK6 GTD too so will more han likely do the same for mk7.
