Honestly, what kind of RWHP gain would I have seen between stock catted exhaust and flowtechs and ORY? I got them installed and it feels faster, but hard to say until I get it to the track with my new et streets this weekend. Give me your opinion. Many told me because of my mph that I was putting down around 340-350 RWHP before headers, is that a little optimistic? PS I hate my predator tune, I don't think it works as well as advertised, and yes, I am merely waiting for someone to come back from vacation to pick up ls1edit. Let me know what you all think...

Headers and ORY could be worth 20-30 hp especially when cammed.
