I got them off ebay. They are aftermarket Porsche 997 tips with a 2.5" inlet and 3.5" dual outlet. They are the most compact tip at about 5.75" long so they worked well.Where did you get those quad tips from?!?!?!?
This was a decent project since it required cutting the bumper openings. I also mounted them on the stock srt resonators so that required some creativity. Well worth it though. The original plan was to mount an e55 rear diffuser but I am happy with just the bumper cutouts and tips.
