All I know is that sometimes while under acceleration, the car will "jerk" and the drivetrain malfunction warning will pop up. After cycling the car off/on, it goes away.

Going back to the CEL's from the catless downpipes.... Are any of you using an O@ simulator? If not, how are you ridding the CEL?
I've done a lot of searching and searching to answer your last question for myself and come up empty for our cars. There's no post out there where anyone comes out explicitly saying they have a solution, and there's no one that advertises a simulator or emulator for our cars. There have been some threads I've found of people trying to pull the O2 sensor out of the stream more (an o2 dedicated logner pipe or spacers) but they all eventually seem to fail for reasons unspecified.

Without a flash tune we are pretty much stuck on the non-TU N63 with CELs. If anyone has seem something that disagrees with this please correct me.
