Default when i downshift

from 6th to 3rd..65+ miles an hour..atleast up to 75..it takes off fine, but when i get to about 4k rpm..its starts bogging or something..lossing power..tryn to catch its breath so to speak...it didnt start doin this till i put my long tubes and ory on...im thinking maybe its the rigged 02 sensors i had to put on it? every once and a while it does it when im in first too..its really annoying an dloosing power..but when i shift to 2nd from 6th at about 55 or so...it hits good! maybe the rpm isn't high enough? its not low though and doesnt start till 4k..so i dont think its the low rpms..gota be an 02??
thanks!

What do you mean by rigged up 02 sensors, and did you have a tune after the headers were installed?

If by rigged o2 sensors you mean you cut and spliced them to reach then it is most likely them. Buy some real o2 extensions and see if that solves the problem.
