At XTR986:
I'm posting a picture of the rear end. It's just and aftermarket fiberglass rear/skirt if you will. It was locally (by the guys at "No Limit") molded/mated to the stock bumper. I spray painted the semi oval shape around the grill to resemble the intakes. I bought it from eBay awhile back. Not seeing them there now..
As for the status of the worthiness of the twins I fear your latter statement applies. I enjoyed them even when only boosting 5psi. They were enough to match the performance of my dad's 2005 Boxster S (3.2). The guys at Turbowerx helped me good throughout the setup and there after but recently was having smoking issues and I did a compression test. At least one of the cylinders is showing reading less than half of the others. Don't know for sure yet what happened but I've been so bummed out that I just left the car (looking pretty).
Next step is take out the engine to know for sure..
