HPX on 2002 superduty
The HPX work rather well. My truck quieted down (after the air was purged out of the line) and it defiantly had a better throttle response.

HPx. Easy install. Quality Product
Just received my HPx and installed it today after work in less than 45 minutes. Took a noise sample before the install and another afterwards to see if I could hear the difference and was pleasantly surprised. The noise was dramatically reduced, my 7.3L idles smoother and I can feel the difference while driving. ++Product and very highly recommend.++

HPx mod
I installed the HPx and the noise was dramatically reduced. I like the feel of the power curve now. Over all very pleased with everything of the HPx mod.

Quality product
I installed this at the same time as the FRX kit to completely solve the dead head issue. Quality build product, fit was flawless. Ford should have done this from the factory

Outstanding product!!!!!!
I was very skeptical that this would do anything, but boy was I surprised it quieted my truck big time while I was driving. Extremely easy to install and very well made. I recommend this product for anyone with a 7.3!!!!

Top quality - easy install
Top quality - easy install 1/2 hour - good directions - much quieter light throttle, but may be due to FRx installed at the same time
