Dyno was nice, now whats next ?

I hit my Dyno on staurday, and was very pleased by what I saw. I pulled a 445 rwhp/432 rwtq after the corrections To say the least, I was very pleased. I have steeda mods: Pulley, X~w/Cats, CAI, and the Steeda Cat back. The tunning was done by steeda, and it was dead on. My Air/Fuel look like a flatline I had a very nice power curve. A small crowd had gathered...some peeps from the shop, and a crowd of ricers. After the dyno, the ricers had this dumbfounded look on their faces....as a betting pool had started on what the car would do. Lets just say I made my dyno fees back and then some.

Now for all you old heads in here, what do I do next ? I have a full length hooker header~Xpipe from my 97GT that was not damaged in the crashed. I took it off to sell, but could I use those on my cobra ? Anyone here using full length, or has changed the headers ? The manifolds on the cobra does not look like they flow great, but as I said I am a newb when it comes to the cobra.

Any advice would be helpfull thanx !
