Decat on MKII

[Taxi Two]

I read many threads regarding the decat on MKII. I just want to make sure that I just need to decat pipe and then disconnect the plug of the 2nd lambda sensor. The car will run without any problem after doing so. Do anyone have the dyno result before and after this mod ? Will it affect the air fuel ratio and cause the car running lean ? Will it weaken the low end torque ? Mine is factory cat, catback but Jetex Laser backbox. Please advise.

erm no before and after dyno sorry butit gives you a power boost thats for sure

shouldnt affect the torque at all sodont worry

Will the car running lean ? Do the car running the safe mode, due to lack of 2nd lambda sensor, or the normal mode.

How rich it will be ? For my current setup, stock exhaust except the Jetex backbox. It runs at around 11-12AFR.
