Which manifold do you have now -- i.e. is your car a 2000 or earlier vs. 2001 or later? There have been a couple of good comparisons run over the years, this motortrend one is very informative: https://www.motortrend.com/news/20-l...ifolds-tested/
The problem is the prices are through the roof everywhere. Used LS6 manifolds run $400 or more, and while the motortrend comparison indicates 22 HP that's on a better than stock motor. Other comparisons show the LS1 to LS6 as being more along the lines of 10 HP: https://ls1tech.com/forums/dynamomet...o-results.html
As I'm sure you've already read on this site, if you have a 2001 or later, it already has the LS6 intake manifold, so now you pretty much have to go with the Weiand or FAST, neither of which is inexpensive.
