    I am not a tuner but have been researching this subject a bit. The '09 head pipe is pretty good and no cat with bung locations near the heads. At that location, the 18mm O2 sensors should be used. If you remove the cat from a later head pipe, the O2 sensors won't heat up as designed and the readings will be erratic making a Vtune or tuning with any auto tuner, like the TMax or PC Vision very difficult.
