I'm an owner of 225 TT and would like to remove the CAT's. By doing so would i face any problems due to the O2 sensors?.........how can i over come the problems if any....
Depending on what yr ur car is. If its an early 2001 model or be4, then u shud be ok, they only have a single lamda sensor, otherwise the newer models have 2, causing problems, and limp modes, etc.
