I understand headers offer decent gains. However, I have heard and read that with the headers installed on the Contour without a decent tune, you don't net much more WHP over stock. Is this true? If so, I am curious if similar gains can be accomplished with gutted pre-cats with a tune. I am pretty sure the headers net you more horsepower vs. gutted pre-cats with a tune due to turbulence. I am just wondering how much.
