Yes, still on the factory downpipe. The oem dp apparently doesn't present a big restriction to the small stock N55 turbo, as evidenced by the small power gains seen on the dyno when going catless. Plus, it looks to be a pretty big pain in the arse to remove/install the dp on xdrive cars. I think a dp would only net me maybe 0.1-0.2 sec of ET and 1-2 mph trap (if that) in the 1/4. To make substantial improvements, I'd need to move to a PS2 and upgraded HPFP, at which point a catless dp would be basically mandatory.
Now if I were regularly hammering the car for 20 minutes straight on a track, doing 1/2 mile events, or lots of 1/4 miles, it would be a different story. But for my fairly modest goals, the factory dp has been adequate.
