I prefer dogs.
Anyway, modern cats are much less restrictive and effects on removal depend on how far you've modded your truck. Sometimes removing them causes more headaches than its worth.
My '02 only has 1 cat which I found kinda odd as many newer vehicles have multiple cats.
Also removing cats can be a legal problem in some states. There are always ways to beat emissions testing but you could flunk the visual and there's always a chance you get pulled over by a cop with a heavy pen and nothing better to do. Most of the time it will give you a better tone with your exhaust if nothing else. Just some stuff to think about.
Oh yeah, many moons ago I sold a Camaro with a custom true dual exhaust to an older guy who was giving it as a surprise gift to his son. He brings it to his mechanic (a straight up by the books guy or **** stirrer depending on how you want to look at it) for state inspection and the mechanic pumped all kinds of nonsense in the guys head due to it not having cats. The guy comes back to me with all this it's an illegal sale crap and nonsense. Basically after sorting through all the BS he was looking to get some money back. We had a discussion and I sent him on his way. Still a lot of drama because of missing cat.
