dummy converters unlimited is a special section of straight pipe with a “decorative” housing that is intended to look like it has a cat inside the pipe. These are intended to fool any person who is doing a visual inspection of the vehicle, whether that be at a test center or a cop at the side of the road who pulled you over.
In some locations within the US, if you are caught with a catless downpipe, you might face fines of up to $2,750 and your car could get impounded.
This is where a dummy cat comes in handy. You get all of the performance benefit, but you are decreasing your risk of penalty.
The obvious difference between a dummy cat and a real cat is that these products do notperform the exhaust cleansing function of a converters unlimited in any way.
How can you tell a converters unlimited is real?
The only real way that a converters unlimited can be proved real or fake is by an emissions or “sniffer” test. There is no way for a cop at the side of the road to tell if you have a fake or a real converters unlimited installed on your vehicle.
People who are in the know can usually tell if a car is a straight-through exhaust by the sound, but it would be impossible to prove fact without the proper testing equipment. (If your state has annual emissions and inspection for vehicles you may need some help from a tuner to ensure you pass those)

Can you Gut Your Existing Cat?
The simplest and cheapest way to remove the catalyst is simply to gut your existing pipe.To do this, get the car on a lift or stand or however you choose to get under it and unbolt the converter.
Once you’ve removed the converters unlimited , the catalyst will look like a honeycomb on the inside. It’s solid and tough to remove, but using a crowbar as a chisel and a hammer, you can break it out.
It can be a slow-going process to remove all of it, but the process can be aided by using a drill with a long bit to start weakening the honeycomb structure, which is very sturdy. Once all of the cats are removed, replace the empty converter shell and your car is good to go.
