I would like ever one to provide a link to their Dyno sheet, those that have done them, and also please list all modifications, especially to the remainder of the exhaust. What I am trying to fiqure out is what is the optiumum exhaust set up with these headers. I know that some guys are showing good gains with the remainder of the exhaust being stock, and some are showing good numbers with aftermarket exhaust. There seems to be a lot of concern with backpressure, so it would be nice to compare all these to see at what point your HP will go down due to a "too free flowing" exhaust.

Thanks in advance, any help is greatly appreciated.
