These headers instantly provided more HP and gas mileage. If you are on the fence about purchasing headers, you shouldn't be, these headers are exactly what I was hoping for. I've purchased a cold air intake, gibson dual exhaust and superchips power programmer over the past years. The headers provided the most noticeable HP and MPG gains. Only issue was the lack of detailed instructions when removing exhaust manifolds. Additional tools required, O2 sensor removal required and not mentioned.

Only had header on my Jeep about a week, but so far seems to be quitter than the old one I replaced that was cracked. I didn't notice any difference in performance. Install was pretty much straight forward, only had a problem with one bolt on the bottom middle. The first gasket shipped with Header was loose in box and arrived bent couldn't be used, had to wait for another one to be shipped, I feel packaging could have been better.
