At any rate, I do feel like there should be a little bit better gain from the headers. Sad to see such small gains, but it is getting harder and harder to produce big gains from factory engines that are already well designed.
The factory headers are 4-2-1 and I believe these are 4-1 so that might account for the lack of power?
