San Francisco Toyota is proud to offer Cap City Muffler's Cat Security™ Plate. This aluminum plate is designed specifically for the 2004-2009 Toyota Prius. Toyota of North America's own Field Technical Specialists (FTS) was also involved with the development of the Cat Security Plate, providing their input to make sure that it will not affect any mechanical performance of the vehicle. Countless Toyota Prius customers have been targeted for their vehicle's catalytic converters. With the cost of a catalytic converter anywhere from $2,500 to $5,000 installed and the possibility of the vehicle not passing smog with the new unit, the Cat Security Plate is one way to ensure the safety of your Prius. San Francisco Toyota is the exclusive distributor and installer of the Cat Security Plate.
