I think I'm gonna get the SLP 1 3/4" headers w/o AIR tubes. The SLP part # is 30005. What installation kit should I get for it? On slpeng.com, there is 2 kits that looked like what I need. One was 88-92 single cat for $68 (part # 30022). The other part was 82-92 w/o AIR for $44.95 (part # 30043). Which one should I get?

BTW, I was going to custom make the exhaust (without any cat) from the 3" Y-pipe so I don't need any of the cat adapters.

92 RS (Rice Sucks) 305 TBI 5 speed T-tops AC stock 16 inch aluminum wheels
14X3 open element, 3.73 gears, posi, dual 2 inch bendable exhaust, no mufflers or cats (kinda loud), 160 thermostat, relocated IAT, weight loss, lots-o-free mods and one hell of a crazy driver.

I have the slp headers w/AIR, the installation kit for it (30022) comes with 90 degree elbows and some extra lengths of hose for the AIR diverter valves.

I assume the installation kit for the non-AIR headers won't have these elbows. Save some cash by getting the kit w/o AIR since you won't be using the AIR anyway.

1989 IROC-Z, ZZ3 shortblock with some bolt-ons.

Don't bother with the install kit if you don thave the AIR tubes. Just get some ARP grade 8 headers bolts.

87 IROC-Z 305 TPI gears, exhaust, converter, blah blah blah ....

 

If I just got the header bolts, would I just have to get some gaskets and that would be all that I needed. How about the mounting hardware and crush-rings? Wouldn't it be best to just buy the whole kit together?
