Given the type of street driving that most of us do, you aren't going to see a big difference between manifolds and headers. For those who are chasing the speed demon, headers are a no-brainer. I'm not 19 anymore and running stoplight to stoplight with my right foot into the water pump. Manifolds are fine for me.
I’m 62, headers are fine for me. Oh, and probably about a 30 pound weight savings too!
