Thats the nbs correct?

Yes

Not for sure about the dynatech systems but i have the single in dual out flowmaster 40 series and they work good on are style truck. As far as headers i am still looking in to them.

If you want to preserve your low end, Tri-y's are the way to go.

Hey those tri-y's look nice. Any idea how much those run? Most of the headers I've seen are like $750-$850. Wonder if the gain justifies the price.

I called Stan's, and theyquoted me $750.00 for the ceramic coated tri-y's
