Correct, any horsepower gained from removing the non-functioning OPF could be attributed to natural variance, there’s maybe 2-5 hp in it. With that said, replacing the OPF with standard over axle pipes helps the sound tremendously.
Going to an catless or high flow cat header will give moderate gains that are more than just variance.
