Pettit Racing Hi Flow Cat RX8
A bad cat can restrict flow, lower fuel mileage, impair performance and even cause engine problems. A Mazda replacement can cost well over $1200.00. This High Flow cat can solve your problems while helping improve your airflow and releasing a little more of the distinctive ‘rotary sound’ that your 13b makes. Not only that but it will save you money while doing it! A direct replacement part with the O2 sensor ‘bung’ after the cat.
