The differences between 4-1 and 4-2-1 headers, if we're talking about properly designed modern ones, are not as great as they used to be.
It's all in the tuning of the length of the primaries and the design of the collector.
If you're serious about upgrading, you either spend the coin for an original system, or go to an aftermarket fabricator like Brodeth, SMT or Mufflerland and ask what's the best design they have.
