Almost new HEADER question. . .please read. . . I read/reviewed over 250 posts covering headers (about the past month and a half) before posting this!!!
The closest to my post is this one from almost a month ago. . .
https://ls1tech.com/forums/showthrea...ghlight=header
Found a supply on one of the websites for Camaros/Corvettes, which has 97-04 Corvette headers available.
It seems to me the flow through these stock Corvette headers should be better than that of stock Camaros. . . With these Corvette headers available cheaper than the Kooks/Pacesetters and all the other brands:
1. Should I notice a decent increase (+10 HP or so) for the change out?
2. With my 01 LS1 Camaro. . . any mods you know of for installing these Vette headers?
3. Which year of Vette headers would be better?
4. Would stainless or cast iron is better?
5. If/while I've got my headers out, should I probably just change out the plugs on my 90,300+ mile LS1 engine while its VERY convenient?
Thank you for ANY inputs. (keep the slams clean)

the stock manifolds will physically bolt up however you'll need to come up with a custom y pipe configuration. the vette LT's wont fit period.
and you suck at teh search if you went through 250 posts and only found one thread not even partially related to your current question. read my tips on how to search in the "getting started" link in the FAQ (sig)
your best bet is too keep your 01 manifolds or simply and highly recommended upgrade to LT's.

What ever you decide I would definitely change the plugs. I would try to find someone selling a used set of Mac midlength headers. They will flow better than the vette manifolds and can be had relatively cheap. That's my .02

Basically all STOCK headers suck. They are designed to be mass produced and offer good low end grunt. However none of them ustilise exhaust scavenging.
Any gain from STOCK Corvette headers over STOCK Camaro ones will be minimal if at all measurable on a chassis dyno.
Either leave them as there are, or if you want more power and power potential there reallt is only one choice. Some long tube headers. Space is pretty tight so no don't try and fit Corvette ones as there will be no advantage in BHP and only hassel in trying to get them to fit, which probably isn't even possible.
Now it comes down to money. There are lots and lots of different brands of header, and it is personal to which is the best. If there is indeed such a thing.
However you won't go wrong with any of these:
Cheap ones - Pacesetter, Jet Hot, Hooker
Expensive ones - QTP, Kooks, Stainless Works
All are good value and performance for the money. Stainless steel is obviously the better bet as it is very corrision resistant, but they will cost more. If you are getting mild steel ones make sure they are coated however.
