Post how to kill emissions equipment

Hi guys,
well my camaro has been taken away by the breakers today, so I'm looking at buying a 1989/1990 corvette to replace it (rather bizarrely I'm importing one from Japan as it seems to be the cheapest way to get hold of one here in the UK),

thanks to the wonderful emissions laws over here for this year of vehicle, I can kill pretty much all the emissions equipment and still pass the emissions tests (<=3.5%CO, HC <=1200ppm), question is what should I kill to increase performance and how?

Obviously change exhaust to get rid of the cat (I was going to fit decent headers too), but what else?

I would leave the rest. Headers and exhaust is most of the offending parts. Egr might be next but it will help control detonation if the fuel is poor, I would leave it.

generally, unless you're replacing the emissions equipment with something better, it's just fine to leave it (headers, for example, are good)... look into performance upgrades, not just "killing" what you already have, and what already works. the engines were designed originally to work with all their parts intact, so you should know pretty well what you're doing (no offense meant - if you do, more power to you) before you mess anything up. and i've messed up my share of things... it's a pain to put them back together if they don't work as well afterwards.
just my two cents... good luck with the car!
