STAINLESS STEEL HPX 99-03
Easy install and it looks good. Not sure about the affects of the crossover but it makes sense to me.

This Crossover Line was extremely easy to install without needing to remove the turbo. No leaks and smoother idle.

Great product
I put this HPX on my 01 Excursion 7.3
It was an easy and straight forward install and the part fit perfectly! It quieted down the "cackle" a little bit. I haven't had any problems with it leaking or anything and I've had it on there for years now. This is another quality RDP part! -
Worked for me
Did the trick for me! Curious to see if it helps with winter morning starts. For now I can say it smoothed out the idle and quieted things down a bit.

The HPX was super easy to install, just use a swivel socket and a extension and it is a 15 minute job. The HPX is not a miracle worker, but it did make my 180cc injectors less choppy and much smoother. It is definantly, no doubt quieter, but other than that there is no other benefits from this, it does everything it claims. Overall for 50$ this is a must for your truck.

Relatively easy to install. It's easier if you remove the intake spider. I went through a couple of O-rings when torqueing down to the provided specs. I emailed Riffraff and they sent me a 4 pack at no charge. Torqued it down just shy of the specs and no leaks! Awesome quality as usual from Riffraff. Super fast shipping too!
