My jeep used to have nothing but a cat, everything after it was gone. Now it doesn't have a cat just a 40 series where the cat used to be and nothing after it. They sound exactly the same...

Leave the cat in - a good cat won't restrict flow, and there's this little thing called Federal Law that really encourages you to keep the cat in place. Why give the anti-recreationalists any more ammo to close our trails and restrict mods in your juvenile attempt to get some more noise out of the exhaust?

A properly maintained and running motor will not produce excessive emissions. I have a well built 4.6L stroker and it passes the sniffer test and is well below the allowable limits.

Dont remove the cat, it doesnt restrict enough airflow to rob you of any horses or make it sound that much different.
