How many catalytic converters are in a car?

I drive a classic car, but I’m worried about the emissions it might be producing. I’m considering adding a catalytic converter to my vehicle, but I don’t know how to start. How many catalytic converters are in a car anyway?

Reviewed by Shannon Martin, Licensed Insurance Agent.
The easiest way to determine how many catalytic converters are in a car is to look at how many exhaust pipes it has. A vehicle will have a catalytic converter for each exhaust pipe—so while most cars will just need one, dual exhaust vehicles will need two.
Catalytic converters became the norm after 1975, and most dual exhaust vehicles have V8 engines. You might need two catalytic converters if you have a 1975 model or older V8 vehicle.
Make sure you take your car to a reputable mechanic for any modifications you decide to make. And to make sure you have the best insurance for your vehicle, let

What are the best snow tires for a Hyundai Elantra?
I bought a Hyundai Elantra at the beginning of this past summer and have been using all-season tires since. The area I live in gets a ton of snow, though, and I’m tired of feeling unstable on the road during winter. Which snow tires are best for a Hyundai Elantra?

Can I get a car loan with a 519 credit score?
My 519 credit score isn’t exactly something I’m proud of, but I’m working on rebuilding it. My only problem is that my current car is about to die, and it’s not worth repairing. I need a car to get to work. Will a lender give me a car loan if I only have a 519 credit score?
