CATALYTIC CONVERTERS

Cats or no cats that is the question.

Federal Law stipulates that any and all emissions controls that came on a vehicle must stay on a vehicle. Just because a certain jurisditction doesn't do emissions testing doesn't make it ok to remove the cat. Say your in a little podunk town and the local LEO is having a bad day and sees a car with super dark tint, loud exhaust and a burned out tailight and decides he's gonna harrass em. Car gets pulled over driver gives some attitude and next thing you know Mr. LEO is looking over the car with a fine tooth comb and what does he find? No cat on a car that's supposed to have a cat. That right there is a federal offence and is a big time fine.

Ok legalities aside

On a DD removing the cat doesn't gain enough hp to really feel a difference. On the track where every 100th of a second does it will. With the availability of aftermarket high flow cats compared to the cost of an OEM replacement if your cat is clogged and need a new one get the aftermarket. If your cat is fine the Ubend delete will be your biggest gain from the cat back. But if your gonna go that far many vendors now offer 3" Downpipes with cats already welded in for cheap.

If you have to ask catless or catted chances are you really don't need to run catless.

Only time I'll condone catless is one car is only running on the track and two your cat is clogged and your wallet won't allow a replacement on your only vehicle at this time. But in this case only as long as it takes to get the replacement not as a permanent fix.

As much as people hate cats they really do some good. The 70s gave cats a bad name but they have come a long ways since then.
