Default Are 99 and 2K LS1 Headers the same??

Found a set of headers for a 99 LS1, but I have a 2K FRC. Are the headers the same? if not what are the differences.

Thanks

Should be the same. Headers are usually grouped 97-00 and 01+.

They changed slightly in 2001, difference being the AIR flange relocated.

:cheers:

If I remember looking at Summit and Jegs... they sell LS1 headers for 97-99 and 00-03....

So I'm gonna say no, but let some1 else who is for sure post. I wouldn't think the heads or anything would be different? Maybe the 99 headers fit the 00 heads, but don't fit past the tranny and in the engine bay.

If it is a header that will fit '97-99 it will not fit a '00. The angle which it mounts up to the mid pipes is different. Trust me I tried when I first got my '00.

Shorties?

I guess the question is are we talking long tubes or shorty headers?

Shorties. I am having new exhaust done also, so my concern is just making sure the air tubes are the same, under the car will all be changed.
