Can a car have 3 catalytic converters?
It reduces harmful exhaust emissions by converting toxic pollutants (byproducts of fuel combustion) into less toxic gases. There are a few main types of catalytic converters but a three way catalytic converter (sometimes called a 3 way muffler) is the most efficient and most commonly used today.
Why do some cars have 3 catalytic converters?
Emission Qualifications
In such systems, one catalytic converter performs standard converter functions, and a second converter sends out a chemical mixture that neutralizes any residual harmful toxins before they vent out.

Do secondary cats have sensors?
The secondary cat’s can be removed from the stock exhaust as well. The data for emissions is coming from the downpipes. From what we have seen of stock and aftermarket exhausts, there are no O2 sensors behind the secondary cats. Thus, removing them will not cause a CEL.
Will a secondary cat delete pass emissions?
With the secondary cats removed you should still be able to pass a smog sniffer test. The primary cats in the downpipes are where 95% of the reaction is occurring. The secondary cats are so far back on the exhaust stream that they would do virtually nothing during during cold start.
