I have a 2000 Z28 with full exhaust and other mods and I'm going to be buying my friend's 2002 Z28 (lower mileage and he's giving me a great deal). I was just wondering: when I take my car back to stock, can I put the exhaust manifolds and Y from his 02 onto my 00? I was just going to use my 00 manifolds, but I sold the passenger side of my catalytic converter, so I'm just going to try to use all of the 02 exhaust if that is possible. I know the 02 manifolds are different, but should it matter if I'm using the whole system?

Will this work?

Thanks for any help.

well, i know the 01-02 are LS7 exhaust manifolds. Chances are it shouldn't be a problem, worst outcome is that you MIGHT throw an 02 sensor code, which is easy to fix.

LS7, no.

The '02 exhaust system is exactly the same as the '00 from manifold to tailpipe other than the EGR provision on the passenger side manifold being blocked off on the '02 style. No other difference.

The cats should bolt up fine. But if you're planning on selling your 00 car with his 02 exhaust manifolds, then it wont be smog compliant (not sure if thats a big deal in your part of the country). The 01/02 exhaust manifolds do not have the EGR connection. You could use your 00 Headers on his 02 car, if you block off the EGR fittings on the header.

Is it not smog compliant simply because it is a 2000 model car? The 01-02s did not even come with the AIR or EGR provisions, so does that mean that they are not smog compliant as well? (I know they are, but is it just because they're 01 and 02 cars?)

It will throw a code because I could simply remove the AIR and EGR, but that's just an option at this point.

The 01-02 have a smaller cam which counters the fact that they don't have egr.

It wouldn't be possible to use his cats and Y with my manifolds, would it? I know that 02 manifolds are different and I'm not sure if his cats would reflect that or not...


BTW 777, that car looks stunning!

2000 exhaust manifolds have the EGR bung on the
passenger's side. On '01-'02 this is just a blind
boss on the casting. '00-'02 I believe all use the
same AIR fitting, '98-'99 differ. The pup-cats and
downstream hardware fit across '00-'02. To put
EGR back you probably would rather find '00 manifolds
than try to adapt EGR fittings to '02 logs. The value
of cast iron manifolds is pretty low and there're plenty
of 'em.

So you said that the downstream hardware fits across 00-02... is that the piping going from the manifolds to the cats? If so, then I will use my 00 manifolds that I still have, reconnect the AIR and EGR with them, and use his 02 cats and Y-pipe. That would be ideal for returning my 00 to stock.

From what you've written, if my interpretation is correct, I can do that. Right?

'00-'02, but yes, '02 cats & Y should go fine with '00
logs.

Awesome to hear. Thanks for all your help so much.

Yes, as Jimmy stated, 2001/2 F bodies have A.I.R. but no EGR.You should be fine if you use your 00 exhaust manifolds and his cats and Y pipe.

Then you can put your headers on your new car, and all it costs is a few gaskets to do all this. Nice! Good luck
