  1. After installing heartthrob exhaust I am getting a P013C code anyone have any insight into this problem
  2. Code is for an 02 sensor. Does the car have a tune by chance?

    There is a chance something is wrong with the 02 sensor, if the car is still under warrenty just take it to the dealer.
  3. Yea I think I'll do that.. Just thought some had this happen to them and could offer a fix . Of course the dealer will it's because of exhaust. we'll see. thanks for the reply.
  4. Did you tune the car after you installed the cat backs?
