Q:I have a 2005 Toyota Prius Base Model 1.5L 4cyl., are there 2 catalytic converters or just one? Show Less
B4neverafter
A:BEST ANSWERHi Brandy, I am pleased to assist you. This is a universal catalytic converter and not vehicle-specific. The 2015 Toyota Prius Base 4 Cyl 1.8L features two catalytic converters, one in the exhaust manifold and another in the underbody exhaust system. Please verify if your vehicle has Federal or CARB emissions. Let me provide you the links below for the direct-fit converters and the universal one (this part you chose) so you can choose which ones you'd prefer to order while the parts are in stock. I hope this helps and enjoy shopping!
