Protect all of the vehicles in your household from catalytic converter theft or give a CatSiren to your loved ones. Select your desired shipping method upon checkout.
When armed, the CatSiren continuously monitors the motion around your catalytic converter using doppler radar technology. If a thief attempts to crawl under your car to saw off your catalytic converter, the CatSiren creates a 130 decibel alarm noise.
