I think the primary use of the car will help shape the decision. Unless it is an all-out race car where every HP counts, I doubt you'd feel a great seat of the pants difference with either TTI item. Just a 2c observation though, not a "real world" experience.
You can play around with some header calculators to compare the output.
http://www.wallaceracing.com/Calculators.htm has a couple header calculators to try, for example.
