any comparisons on non catted C5s. I changed from LGs to Kooks 1 7/8 to 2 inch stepped headers. Installation was a nightmare. I dynoed 503rwhp on a mustang dyno with the LGs and after the Kooks were installed I dynoed 450rwhp on a Dynojet (reset A/F during the dyno session) WTF. Is it the dyno or did I loose 50 rwhp? I took it to the track, times and MPH stayed the same.
My guess is one of the dyno's are incorrect. I hate to think I spent 1400.00 to loose 50 rwhp. Hmmmmmmm

Are they new Kook's? If so, maybe THEY copied AR's design and moved a tube. Naaa, that could never happen. But I do see they are running merge collectors now. Go figure.
