In addition, exhaust clamps are used to ensure a tight bond and provide additional attachment strength. Features a heat-activated adhesive strip (black-side) that creates a tight bond to the exhaust system to prevent removal. It's an expensive repair, and probably the end of the economic life for a less valuable vehicle, but an expensive catalytic converter replacement is a part of owning a high mileage car from the last 20-25 years, especially in California.The CatStrap™ is encased in a high-temperature strap that runs down the length of your vehicle's exhaust and converter. Unfortunately, being an 06 in California, all the monitors (except Evap if the smog station is willing to accept the hit to their STAR score to pass it) need to be completed to smog and register it. If the above is more than you are able to do yourself, sell it and get a newer/lower mileage one, it will be far cheaper and less frustrating. If so, you need a new cat but you can leave it that way until it needs to be smogged again, or if the smog people don't notice. If the check engine light comes back on again in a short time (before the catalyst monitor shows complete or shortly after), try putting a spark plug anti fouler (you will probably have to thread two of them together and drill out the bottom of one and thread it to the oxygen sensor, and thread one into the cat that's not drilled), and see if that keeps the light from coming on. With your new OBD2 scanner, see if the catalyst monitor will run and show ready/complete before the check engine light comes on again. If the oxygen sensors haven't been changed in the last 80k miles, change them. Get an OBD2 scanner too if you don't have one so you can clear the code yourself.
