The AWE exhaust for the MK6 GTI is a best of breed system that features fully mandrel bent tubing, thick .065" wall T304 stainless steel, multiple slip joints for easy adjustment, and a signature sound track that only AWE can deliver. The Cat Back system is topped off with 102mm slash-cut tips in Chrome Silver. The AWE Performance Cat Back Exhaust mates up to the stock downpipe, ready for action without affecting emissions equipment. Why did we choose 2.5 inch and not 3.0 inch diameter for our MK6 exhaust? Our first 2.0T exhaust prototypes were indeed 3.0 inch, but we found that the effort it took to move the large mass of air in the 3.0 inch system at lower RPMs resulted in a loss of torque with very little offsetting gain up top. If you're upgrading your MK6, you owe it to yourself to go with the VW OGs.
