it would increase the HP

does your state have smog testing? You might want to keep them on if they test.

It would increase HP and give you a deeper exhaust note. You could do cut outs too... my friend has them, but personally, I think they're kinda worthless. Removing the cats would be your best bet for what you want, depending on emission laws in your area. Where do you live?

Get an x pipe with thoes mods is should sound great.

HAHA, save the environment!! Look I live in CA, like the capital of all emissions testing, and I dont have cats on my 91, they only see use when I need to pass smog once every 3 years, cats are restricting, get rid of them!
