Shorty headers for lowered 4x4

[Tlee94sbc350]

Since I've got my inner and outer fenders off I've decided to ditch the old truck manifolds and grab a full new exhaust. Who has run shorty headers with out fitment issues? And which brand? While I'm at it im ditching the cat. This is a 94 k1500 5.7

Summit Racing (made by Pace Setter) G9015 if you have A.I.R. or G9014 for 88 - 95 trucks. They bolt right up to the original Y pipe, or you can go with whatever you want.

What do you mean by A.I.R? I have a 94 4wd 5.7

What do you mean by A.I.R?

Air Injection Reaction (or something like that) aka Smog Pump. It's supposed to help fire off the cat when cold. There's a port on each side for that A.I.R. pipe. This was required in CA and some other states. Federal requirements didn't call for that. Here's a picture of mine.

Thanks - as a side note, I have aluminum heads with slant plugs. The rear 2 plugs on both sides need heat shield sleeves. I melted the boots on the driver's side within a couple days and the passenger side were softened. I don't even think I could get ceramic boots on the plugs since the boots don't flex much. You could wrap the headers instead.

Cheap and effective. I just put some on my Stepside after burning through a plug wire.

Do you keep the pre heater tube that goes to the bottom of the intake when i replace my manifolds with these headers?

I didn't, but I live in the south. If you're going to keep it you'll have to find a way to attach the heat shield to your header.

The G9015 headers came with an adapter tube that mounts on top of the #2 tube IIRC, they have a CARB (California Air Resources Board) order so they're legal in all 50 states. I didn't use it since I removed the entire intake box and closed filter housing.
