Guardian-Secure Catalytic Converter Antitheft Alarm exhaust vibration detection

Description

Protect your catalytic converter with our easy to install undercarriage alarm. Simply mount the alarm with its industrial 3M backing to any flat portion of the frame or vehicle. Attach the sensory strap to the exhaust pipe and you're good to go. Any vibration detected along the exhaust will trigger the alarm and produce an ear piercing siren sure to get everyone's attention.
Unlike other alarms, Guardian alarms have a solid aluminum case to protect from heat, shock and the wear and tear you expect to find under your vehicle.
Each alarm comes with detailed instructions, keychain remote, alcohol pads to clean the mounting location, and a "Protected by Guardian Undercarriage Alarm" sticker to warn thieves that your vehicle is protected.
