my original stock exhaust is still tight, no leaks, so i haven't tried the new stuff yet - the headers & y-pipe are still chilling in their boxes, sorry.
from cross referencing the factory exhaust manifold part numbers for my 1999 2WD to available direct fit shorty headers i came up with these :
the passenger side is S10 but the driver side is 1996-98 full size truck.
note that i haven't tried mine on yet because the original exhaust is still good & i didn't want to cut it all off yet, so i can't confirm fitment. :shrug:
in your picture note how far the driver side center pipe sticks out before it turns down compared to the pic i added.
also the headers in your picture have the smog/air pump fittings (with caps & bolts if you don't need them), my van doesn't have the smog pump.
Not to burst anyone's bubble but GM has always been known for the worst design in Y pipes. they double pipe them which makes them tiny inside and the bends are horrible on flow. Point being if your going to install headers you may as well get a Y pipe custom made using one of these.....https://www.ebay.com/i/402431746616?chn ... CoEALw_wcB
That's the reason I asked Mark.
I had to weld a crack in one of mine so I'm thinking new headers and a set of sidepipe in the spring. I'm looking for feedback from an astro safari user from the V8 club regardless of the thread title...
Finally getting around to installing those pacesetter headers I posted 2 years ago, lol.
I now know why there is a different part for the 2003-2005 headers... The side with the 2 ports on it are for the air injection system which isn't present on my van. also, the middle pipe sticks out too far and will hit the frame.
Bummer... so it looking like those JBAs are the only option for the 03-05. Is the frame different on the 03-05? I'm wondering how akforceten was able to use them on a 2000 AWD Astro.
the frames are not different.
can't just say "those JBAs", they have many
here's mine, I had looked at a lot of stuff and made a calculated risk that they would fit. dunno if I was right yet.
these are for an earlier full size pickup

Sorry, I was referring to fire57's post of the JBA 1840-S3 headers he has on his. The strange thing is, the shape looks about the same as the pacesetters that akforceteen used. I feel like I'm missing something if the frame is the same.
EDIT: I am missing something, its not the frame its going to hit, its the body. I think my 2" body lift might not be enough, everyone with headers mentioned a 3" lift.
What is the part # for the ones you posted, those look tighter.
There is another model without the air injection tubes on the front primairys (hahha) that is the same shape. But when mine came up, they were too good a deal to let pass by.
