The performance without headers you can feel it above 2.5-3Krpm, but now with headers it increase to 3.5-4Krpm.

NP. Straight-through or not, it looks like you got the sound and performance you were looking for. I had an N1 style straight - through on my Echo, which gave great low end, but was a bit too loud. I think I might try a dual-out muffler like yours, on my gen 2 Yaris.
