I'm was wondering what would happen if I took the catalytic converter out of my '88 Ranger (2.9L V6) and replaced it with just a piece of exhaust piping and put a glasspack muffler on too. Would I get any power/mpg out of doing that? I could care less about global warming so I don't need to hear about how terrible I am for causing a tiny bit more pollution.

What would happen is you'd be breaking federal law, increasing pollution, and not doing much of anything to gain any performance by removing the cats. While you are obviously a really classy, mature, and educated guy to say "I could care less about global warming so I don't need to hear about how terrible I am for causing a tiny bit more pollution", it's not so much the impact you'd be having on the environment as much as it would be having a negative impact on the air we breathe. Yes, that's right, there are other people on the planet besides you.

By the way, to say "I could care less" means that to some extent, you do in fact care. So since you said you actually do care about the environment and pollution, leave your cats alone.

you wont gain anything from it besides having an obnoxiously loud truck. And like Jay said breaking federal laws and the pollution stuff. only reason i have straight pipes and glass pack on my truck is they were on when i got it and cant afford to get it all fixed yet so i don't drive it.

on the stock 2.9 you will actully lose more power because you lose the backpressure the cats provide to the motor. did it on my b2 and dyno'd it when i was at school and it was not worth it. put a good muffler on it (flowmaster) and that about all you can do to gain performace on the exhaust side besides headers

Awesome! Because as we all know, diesels suck and don't make any torque unless you do that.

x2 on loosing power, did it on my sisters 2.9 and never was the same

Ok thats what I needed to know. I like loud trucks and my neighbors are cool enough not to care. Glad to see Al Gore's little beotches are everywhere. I live in the country; the air is fine here and my little truck will never pollute like those big diesels do anyway. I would love the opportunity of Gore coming to my house... Lots of federal laws lose their significance when you consider the idiocy of those making them... Anyways thanks for the posts that were helpful. I knew it helped on the diesels but that's good info concerning the cat. on my truck. thanks

I for one like to breathe the air in my environment. I could care more.
