Well, my friend wants to go with some headers and a y-pipe but doesn't have the $$ for the air injection headers. Emissions are no problem around here, so we will take off the cat also no doubt. He has a 90 IROC L98, ported heads, SLP cam with juts a Dynomax catback now. Any suggestions would be great, including best headers for the $$ and etc. Thanks!

 

yes he can get rid of the smog (A.I.R.) crap. he still has to keep his O2 sensor though. as for headers, slp or hooker super comp shorties.

 

If you wanna go crazy, get the LT Hookers. You will need to have an O2 bung welded to it though. And you will need to reroute your accessory belt, I needed a longer belt when I eliminated the smog pump. 968K6 was my belt size...

 

i deleted my smog pump and my air tubes, hoses, and that black box.

cars still runs good.

i am running this belt setup

what did you guys do to the black box wires??? I dont know where to out them!

 

just taped them up to that hose.

 

after u take off your smog stuff, will it cause a code to be set or for the eng to run funny ?

 

It won't cause any codes. The ECM only sends a signal to the air pump solonoids, it doesn't get any feedback whether it worked or not so it will not cause any problems what so ever.

 

what a reliefe! no code??? gm must be slipping lol

ususally i get a code if my cars is dirty

 

Im in the process of removing all my air crap too....is the thing in the middle of the fuel rail anything to do with air? I think its the EGR valve? whats that do?
thanks

Oh yeah, Im stuck! I cant get to the bolts on my stock exhaust...

DAMNIT!
LOL

 

Yes, thats the EGR valve. You need to leave that on unless you burn a new chip or you will get an error code.
