This is the 2nd time I have purchased PaceSetter headers. This time it took a lot longer PaceSetter to ship them out (about 3 weeks). There was a small hole in one of the welds (which I fixed myself), so make sure you check them over b4 you go to install them. Also, check to make sure they are both for your engine. I spent 4 hours taking off the old manifolds only to find out that they sent me one header for a 4.6L. I contacted Pacesetter, and fortunately, they found the correct header at their manufacturing facility. They overnighted the correct part to me. Apparently this has happend to others, so make sure you have the right pieces b4 you spend the time taking apart your stock set up. The gaskets the come with the headers are not very good, so make sure you pick up a better set that will not burn out so easily (I used XX carbons).
Now that I have them installed, I have a much smoother and consistant power band, along with the added torque. Please note that I also have a MAC air intake, and true dual exhaust. Based on my odometer readings, my mileage is noticably better.
