Dual Exhaust. Standard cars contain an exhaust system, or a set of pipes that guides exhaust gases away from the combustion in the engine. Each exhaust typically works in conjunction with one catalytic converter. Cars with dual exhaust systems carry two catalytic converters, one to neutralize the emissions that emit from each set of pipes.
Cars can have more than one catalytic converter for the same reason cows have four stomachs: the product that comes out is more desirable to that which is downstream in the exhaust/digestive system. In the digestive tract of a cow, the upper intestines are able to process well the food that has been through not one, not two, not three, but four stomachs.
Why Does a Car Need Two Catalytic Converters? – It Still …
Newer high-end vehicles are now coming equipped with two catalytic converters as part of an even more stringent emissions program. The first converter breaks down the exhaust as normal, while the second acts both as a filter for tiny particles and a pump which releases a chemical mixture that further reduces any harmful gases which may have escaped the first converter.
There are cases where a vehicle has multiple catalytic converters to keep up with emissions regulations. In that case, the engine’s gases go through conversion twice and should come out of the exhaust as extra-clean emissions. Why Does My Car Have Four Catalytic Converters? Even though cars can have more than one cat-con, it’s unlikely that yours has four.

Why do some cars have two catalytic converters?
Cars with dual exhaust systems carry two catalytic converters, one to neutralize the emissions that emit from each set of pipes. Some modern and high-end cars follow more stringent emission qualifications, which require additional neutralization of toxic emissions.
How many catalytic converters does a V8 have?
The straight inline engine has one exhaust pipe, one catalytic converter is needed, cars or trucks with V-6, V-8 or V-12 usually have two catalytic converters, because there are two exhaust pipes on both sides of the engine. Will my car work without the catalytic converter?
How many catalytic converters are in a dual exhaust system?
Cars with dual exhaust often have two catalytic converters — one for each set of pipes running from the headers to the rear of the vehicle. Newer high-end vehicles are now coming equipped with two catalytic converters as part of an even more stringent emissions program.
What is the effect of heat on a catalytic converter?
The catalytic actions all dependent upon heat generated in the Catalytic Converter. Heat has the additional effect of generating expansion in whatever material to which it is applied. With the addition of the compounds (above) being collected by the Cat within the matrix, these compounds become a blockage in the system.
