basically the 4-1 design allows for less restriction than the 4-2-1 design and looses some low end torque, but gains higher end hp.

i can't wait to see the FS 4-2-1!!! if it's as purdy as the 4-1 i think i might just buy one.

<font size="2" face="Verdana, Arial">For the record, an ALL (and I mean 100%)stainless header will cost close to $900, so that is something to think about. Ours will be less than five hundred easily. Don't get me wrong an ALL stainless header with excellent build quality sounds great, but most people aren't willing to drop that kind of coin.
