I've been trying to get my 10 y/o son out of the house this Summer and off of his computer. So I've been using that as an excuse to order a lot of parts here and use them to teach him how to work on vehicles rather than how to build stuff in minecraft. I have to say, this was such an easy install my boy almost did the whole thing himself.

I ordered this tube to replace an old crossover tube which was made out of hydraulic hose and had begun to leak. This stainless steel crossover tube is far superior quality compared to the old tube, and has greater inside diameter for oil flow. Didn't notice much difference in noise level, but the engine does idle smoother than it did with the old tube. And, it is nice to no longer have the crossover leaking oil.

The HPX substantially quieted my engine down and reduced cackle. It is definitely a product I would recommend to anyone who wants to quiet their engine down.

Got this to replace my braided crossover tube, flawless fit good clearance every where and install might have taken 10 min. Great product

Pretty easy install. Works great, no problems getting hooked up. High quality compared to the one I had on my old truck!

Quality and fit is right on point!

Excellent product by Riffraff Diesel, fit and quality were perfect, directions we outstanding and easy to follow for my 2000 F-250. Made engine idle smoother and less noisy, highly recommend.

Probably the simplest upgrade I've done yet. I've done the FRX, which is now a fuel bowl delete because aluminium fuel bowl, and banjo bolt upgrade as well but this one made a huge difference in reducing the cackle and smoothed the idle even more. Great quality from these guys.

Fit like a glove, easy to install and no leaks! Does quiet engine down a bit at idle and seems a bit smoother too
