taking out a cat?
i need to know if i can take out my catylitic converter and just run a straight pipe from the turbo back to the end of the car with 3inch piping. can i just put 2 of the sensor holes in the piping where the sensors go? will it mess up the air to fuel ratio? i know i wont pass emmisions but ill be putting my stock stuff on when i go for it in about a year.
