i have an 05 gt and im up for emission testing. I have an off road h pipe and i have a 93 octane tune and an intake. I have no check engine lights butwhen they plug the obd port are they going to see the 02 sensors are off and fail me..? Also am i going to be able to pass it iwth the off road h on the car? Do they look for cats? Also my car smells like burnt oil does that matter? What do i need to do to pass?
