Noobie question on Smog checks/exhaust
Hey everyone,
What exactly can I delete that would still pass California smog tests? Thinking to go with 3in piping+m5 mufflers but I was wondering if I can delete resonators/cats or if I should keep everything stock and just change the muffler+piping. Any input is appreciated |
