Header differences - later c5 vs early models
A friend has a set of B&B headers he is going to give me off his 01 z06, and i want to put them on my 99 frc. I know there is a difference with the location of an air line on the headers. Could someone elaborate on this difference? I was wondering if it is possible to put these headers on due to that difference. If so, could someone please tell me how it is done?
Thanks

is it possible to re-route it? fyi these headers are bolt-on. it should be like putting late model stock exhaust manifolds on an early model. just need to know if this can be done.

If you are talking shorty headers they won't work on your car, beside the AIR tube flanges being in different locations the collector flange is at a different angle. If you are talking about long tube headers the only difference would be the location of the AIR tube flanges and it should work you will just have to rework the AIR tubes. If you are interested in a set of shorty headers for a 97-99 I've got a set I bought by mistake thinking I could make them work on my 04. They are in excellent condition, and I'm fairly close to you. I was going to put them on the forum one day. I paid $275 for them but I'd take $225.

I have re-read your post and you are talking about shorty headers. The headers your friend has will not work on your car. You cannot take a late model stock exhaust manifold and bolt it on an early model car because the angle of the collector flange. You could make the AIR tubes work or do away with them but the headers will not bolt up at the bottom.

you can make the 01 shory headers work on your 99, by doing three things:
1) cut the passenger side AIR Pipe and re-connect with a piece of hose and a couple of clamps
2) bend your engine oil dipstick tube to fit or buy and install a dip stick tube and dipstick for an 01-04 C5, AND
3) buy an H-pipe / collector pipe for an 00-04 C5

Look again at original post...............he's talking about
B&B shorty heanders, which many / most forum members believe to be the best by far.......both in terms of quality and horse power gained. Believe these run almost $1000 new, and superior to most 'cheapy' shorty headers.

Thanks for all the comments guys. I'm going to do a comparison this weekend to check things out. I'll let you know how it goes. If they absolutely cannot work, i may be interested in buying those shorty headers from ljthe2nd. ;D

Yes that would work but that H pipe with the cats would cost more than if he just bought the correct shorty headers, and I'm not sure if the O2 sensors are in the same location, extensions might have to be bought. Plus if he bought the correct shorty headers he wouldn't have to do anything to the AIR tube flanges everything would be correct and just bolt right up.

OR,
Why not take your buddies headers,and swap them for the guy who has the ones you want?
It seems he wanted the late model design,at least at one point.
Just another thought.
If that does not work out,I would just buy the right ones the member has for $225,that's a great price!

yes i could buy the shortys for 225, but if i can get more hp out of the others, why not? one of the welded flanges is messed up on my h-pipe anyways, so im going to replace it one of these days. i could probably get the h-pipe for around 80 bucks right? sounds to me like thats all i really need. If i end up needing the sensor extensions, where can i get those? i'll probably go ahead and order them just to be on the safe side.
