Default c6/c5 header help

He states they are for c5 and c6. They have the a.i.r hookup so i would think that they are for a c5.

c5 heads will only fit a c5 and c6 heads will only fit a c6 so the local feller needs to be more clear as to what gen they fit and what year as well..

Get what your saying. He does not know exactly. Seems to be and honest guy. But i though with the a.i.r hookup that they might just be for a c5.
The price is awesome.

If they have any kind of identification numbers on them, give LG a call and see what they say. Maybe even send them a pic of the headers.

be careful, those certainly don't look like LG headers to me... their collectors are slip fit and do not use flanges with bolts... the way the primaries are routed doesn't look the same to me either

This is exactly what I was thinking too. Tread with caution for sure.

And I believe the air tube location on the passenger side changed during the C5 run (or different from LS6 to LS1). I ran in to that problem on a used set of Kooks I found. I had to remove the airtube and have it welded to another primary.

They favor some of the Chinese knock-offs to me. Unless the price is outrageously good and he has all the installation parts I'd be afraid to take much of a chance, especially since he does not seem to know what they fit. I assume he was running them on something. What year Corvette did he have? If he acquired them just to make a buck on them, I'd steer clear.

I would steer clear of those.

If you want decent headers for a great price check these out: http://shop.huronspeedproducts.com/X...m-XSPC5LTH.htm

I never installed these but you will find many good reviews about them on this and other forums.

Those are not LG's. Even if they were LG's, they only make primaries that long in the 1-3/4", not 1-7/8".
