Will this fit my car?
The product fits 2.5'' inlet / outlet, and there is a compatibility list as a guide on the page of Vehicle Fitment for you. If you are still uncertain, please contact with the customer service.

O₂ sensor plug direction? pre cat or post cat?
The cat isn't directional, so you can flip it around either way, as long as the O₂ sensor plug is conveniently located with the O₂ sensor.

Is it approved by California?
Sorry, no. It is prohibited from sale in California, Colorado, Maine, and New York due to State emissions regulations.

Welded or flanged?
Just installed to existing exhaust system, both ends may require cutting and / or welding, please better ask for professional assistance.

What to do if check engine light comes on?
Ensure that the gas and oil caps are on tight and that the oil dipstick is seated correctly. If the light remains on, it could be triggered by a faulty oxygen sensor, wrong installation of catalytic converter, bad spark plugs, malfunctioning thermostat or bad mass air flow sensor. If none of the above is true, please contact with the customer service ASAP.
