Supercharger Vs Headers

[Centerfire]

I was discussing adding a supercharger to my H2 with Jan D from Realwheels. He brought up a conversion with the people from Balanger Headers (Not sure I spelled correctly). They told him of a test between an H2 with a supercharger and onw with the Balanger Headers(sp). They ran duplicate Numbers in the quarter mile. This is all the info I have.. Anybody else have more.
We also discussed exhausts, as they are now selling Corsa.. Realwheel tested Gibson, Borla, Corsa and a couple others on their Yellow H2 for the SEMA show. They found that the Corsa had the best performance and sound of all tested.
