Performance Specialties did an outstanding job on my vehicle. They went out their way to save me money on the repairs. In economy, nobody can afford to buy a new car and we have to keep older cars going. Performance Specialties helped me do that. Performance Specialties replaced the catalytic converter in order to clear the Engine Light. I was worried that the problem might have been the O2 sensor so they put a working sensor on the vehicle to verify at no additional cost.The problem was still the cat which was expensive to replace but I appreciate their going the extra mile to try and save me money.
