It won't harm, but if your exhaust is stock it won't help a thing either unless your cats are clogged. If they are clogged then replace them with a high flow cat and a cat back system. Better performance and cleaner air.
What is this fascination that everyone seems to have with removing their cats? Do you breathe something other than air?

i think its just that the 300 has two of em that makes people angry. I'm going to be taking off the second one, i don't see a need for two cats on an engine thats only 300 cubes.

I do believe I am getting a lot of restriction from the 2 cats. but they are so expensive. If i could get a cheap cat that would not restrict the flow I would get it. plus this engine is putting me in the poor house using fuel.

Maremont's hiflow cat set me back $100, and I breath easier for it. It's less restrictive than most stock mufflers. Coupled with the Hooker aerochamber, it sounds mildly mean and burns nice & clean.
Gbick - removing the (good) cat(s) will only harm the air. As for restiction, ONLY a damaged cat will create THAT MUCH restriction - I'd recommend going with a single hiflow if the emissions folks will let you (my '82 only has the one). I've almost doubled my HP -and enjoyment - even with a cat.

very true broncr, that is pretty cheap for a cat. I live in central maine where emission laws are non existent. But those i6's are emission pigs. but with the cats plugged it tends to burn more fuel to get the lost power, there by creating more emissions

Yeah, a plugged cat is an all around waste. It's not doing it's job - it's actually worsening the problem it's designed to help with.
Here we have a similar problem that is just as maddening.
It's the "oxygenated" fuel they force on us in the Winter months. They claim it costs more (naturally) so the price goes up. It contains 15% ethanol or mtbe and has a net effect of reducing gas mileage by almost the same 15%.
I've never heard anyone do the math to figure out if we're actually reducing pollution enough (by adding the crap) to offset the additional gas burned ( and pollution created ) to get anywhere. You pay more to get less, and use more to get to the same place. It mus be sum reelly good stuf.
