Can anyone tell me if the '06 model has a cat converter in the system, and if so, where? Stock system. I want to weld in a Oxygen Sensor bung and want to make sure it is placed correctly. The guy who is going to do the dyno has asked for me to get it fitted before I get there. Bear in mind that this is an Australian model so there may be differences due to legislation etc. Someone may know but I can't find anything in the manual. If all else fails, I'll call the dealer. Thankyou.
