Here's a dyno
Dyno graphs shows testing with 04 WRX catted downpipe, uppipe, exhaust, versus addition of manifold only.
Let me know if you have more questions.
Thanks,

If so, What kind of numbers could one expect from a reflash with the same above mods?

i am going to get a set of these headers. where can i get the ceramic coating done? what are the real cons about wrapping the headers? what are the cons to the new headers compared to stock? Will it hurt the headers driving in cold weather and cooling off too fast and what about long trips? What is the tap made for on the headers?

What do you guys think of these ebay headers: http://cgi.ebay.com/ebaymotors/T-Pro...spagenameZWDVW
Are these copies of any name-brand header? Does anyone have a set installed? If you do...Do you still have the rumble sound, and what about performance?
