Personally I run the soft, but there is nothing better about it that doesn't fall into the theory category.

Will the same line work on both the 7.3 and the 6.0 ?????????

I don't believe so PaulwestSki.

Is there a different version for the older trucks, or do you have to re-route the HPO lines?

BTW, it does appear to idle smoother, and quieter.

On the OBS you need to move one of the HPOP lines to a different port so you can install the HPX. Sorry I didn't see this sooner!

Does someone make a line for the 6.0 or is this not an issue on the 6.0??

I see someone posted something about ITP's HPX not fitting early 99's, but I have had it installed on mine for a couple years now. Fit like a glove

I installed the soft hose from clay at riff raff and it is a great product. Well made to with good materials. I will never have to worry about any problems with that things. And as for the noise, it does idle a lot smoother and noise is slightly less as well.
