yes its another header question...
would I be better off getting headers with emissions fittings or without? My car is a daily driver when I need it to be. Do the non-emission headers require different tuning?

It all depends if you need to pass smog.

No I don't have to worry about emissions testing. I'm just curious as to whether there would be any difference performance-wise. I will get the set with. Thanks guys.

Ed's car is all about smog! Im running race headers(no emission fittings) and it looks so much better in there. You can either get headers for 98-00 that have AIR and EGR or you can get 01-02 headers that have AIR only. It all depends on what you wanna do.

Without the cats I won't need the AIR fittings, but what about the EGR? Will blocking it off or getting rid of it have any adverse effects?

while you're at it, remove the air pump and hoses. This will clean up the engine bay, and save about 10 pounds.

I am of the old opinion that unless your getting long tubes dont bother with headers. The stock manifolds arent super restrictive on these cars. I have seen guys go from stock mani to Mac shorties and not even run a tenth better.

Usually if you pass that you wont have to do a sniffer test.
Just remeber when running catless, you will smell the unused fuel. so it will smell as if you car is running rich when it isnt.
Also for the AIR and EGR provisions, block off plates will work fine! w/o any problems
