This is a well made, easily installed part. It seems to have mildly smoothed out my engine, but it was already pretty smooth to begin with so it didn't make a huge difference on my 7.3L. Still I think it was worth purchasing, and installing. If you're looking for a high pressure cross over kit, I would hands down recommend this one. Why buy a rubber hose that'll eventually wear out when you can have a meticulously bent, compact, and in my opinion beautiful stainless steel tube?

This definitely did what it said it would, much quieter in the cab and very smooth. Total time to install was less than 15 minutes. I have already showed several friends and they want one.

I installed it on my 03 f350 with 7.3 6 speed I noticed an instant reduction in vibration and loping when I put it in gear well worth the money have had it more than a year and no issues.

265K miles of smoother idle, and quieter. A quality product.

Can't say that it made my Excursion any quieter but it does idle smoother with the cross over line. Too soon to tell about mpg improvement but worth it for the idle. Setting in the drivers seat, you can't tell the truck is running except for that lovely diesel sound. The hardest part about the install is reaching the ports, very easy to do, just be patient.
