Cat converter - after muffler

Will it cause any harm if I install the cat converter after the muffler? Is this also legal and will it pass inspection in Va?

No it will not pass inspection and the cat will not do its job. The cat has to b close enough to the engine that the exhaust gases can heat it up, hot enough that it will actually burn off hc and nox etc. sticking it behind the muffler will do u no good

won't work. the cat needs to be close to the engine so it can heat the cat up to operating temps.

English?

water is a byproduct of combustion. condensation out the tailpipe is totally normal.

If you feel so inclined, go ahead and place the cat after the muffler.

When you get back from failing visual inspection, you can pull the cat and reinstall it before the muffler in the stock location.

Do it right, or don't do it at all.

I think it's a great idea. As a matter of fact you should get a patent on it. I cant believe that no one in the auto industry thought of this yet.

He's asking why do you want to put the cat after the muffler? What do you think it will gain?

Thanks for all of the positive comments and warm welcome. The reason I asked is that it is already on that way. Just wondered if it was illegal or could cause any problems

Clear and effective communication is important, even on the internet. Your original post indicated that you were thinking of installing it that way, not that a previous owner had already installed it that way.

People do dumb things to Jeeps. Call them redneck repairs. I suggest you take the vehicle to a shop to have the cat installed correctly.

If you are even considering doing your own repairs and upgrades, I recommend you get very familiar with your vehicle and know part what does what and how it does it.

I also recommend taking out your air filter and airbox to limit restriction of airflow lol
