Header difference 97-00 and 01-04
Whats the difference between 97-00 and 01-04 headers.
Will LT's for a 97-00 fit an 01 without mod? I know the headers will fit, just looking for any mods that may have to be done.
I tried searching for it, but couldn't seem to find the differences.

The only difference is the location of the air tube fitting on the passenger side. The 97-00 headers air tube fittings is on the header pipe closest to the firewall, and the 01-04 have the tube located on the 2nd pipe closest to the firewall. Driver side are all the same for all years

It might help if both the original poster and anyone who replies qualify which header systems they're referring to...

Its not the header manufacturer that determines the difference, its the air pipe location that the model years have that the manufacturer has to match up to. So to answer your question, yes, all locations are the same on all headers to fit that particular year of car.

On the later cars, the tube mounts more forward and bolts to the cylinder head.
If it were me, I would have the AIR system tuned out and get a set without air tubes or have them eliminated or blocked off!

silly question but can't the dipstick tube be bent ? are they *that much different? maybe buy a tube for the appropriate header. asking for instance if a deal on headers came along but not the right year.

LOL!! I imagine anything is possible BUT,,, the complexity of the bends and the possibility of KINKING the tube makes it not worth trying. You would also have to weld on the correct mount bracket.
The Tube and Stick are a matched set. Do NOT try to use a early stick with a newer tube or vise versa.
Ive put BOTH tubes on my 02 ZO6 just to see if they would fit I have Stainless Works headers and it has the fitting on exhaust tube #6 to mount the early stick.
97 frame with stick between cyl 4 & 6
Remember,, the 2001+ stick mounts to the cylinder head to the rear of #2 exhaust tube>

The later dip stick will fit with the earlier headers as is.
No need to get in a panic about the dip stick.

I just put a a set of 97-00 on a 02 two weeks ago. Fit with no issues, lucky me I had an old 00 air tube in the parts bin and swapped it out to make that fit, the one in the car had a bad valve anyway. The dipstick bolted right up to its original location.
