I have been running the stock cat back with stage 2 and a 3" downpipe for two years now. I have no boost creep, am hitting 16.2 psi max, and my egt's at the manifold max at 820C for normal driving and track days. My car actually ran hotter on the highway at 130km/h using the stock map. The upside is my car is still quiet for the cops but it does not hold boost very well to redline. I have compared mine to a friends with the cobb tbe and his does hold more boost and he is only hitting 15.8. The drop in boost becomes noticible at about 5000 rpm and i am down about 1.2 psi at 7000 as compared to his car.
