supermaxx header gains? dyno or track results? I need headers with cats for legality issues where I live, no emmisions just need cats. Anyway I am leaning away from flp and toward supermaxx because of the stainless construction. Anyway. Anyone have a dyno chart of these headers on a stock cammed LS1? or have track times as a result of gains from these headers on a stock cammed ls1?
I have seen the chart of a 36hp gain on a ls1 with a good bit of mods https://ls1tech.com/forums/showthrea...ight=supermaxx
I plan on a tr230 or similar cam in the near future, but for now I just need the headers.
Help me out.

I just put them on a '98 Z28 July 3. They are currently running through the stock Z28 catback. I am getting a SLP dual/dual system with a cutout soon and will dyno it again then. The car made 300/320 with only a lid and filter. SOP I'd say it picked up ~15rwhp through the stock exhaust.
