    Beautiful parts

    You really have to see in them in hand to appreciate all of the machining and engineered excellence. This are quite the piece of billet to hold. Perfect fit, and the stainless hardware really compliments that install.

    Strong & beautiful

    The website pics don't do these pieces of artwork justice. They are amazing in person, the machining is top notch, and the oring is so much better than RTV. Even stainless steel hardware and billet standoffs for the brackets are first class. From start to finish these are head and shoulders above anything thing else on the market, period.

    Very Good Fit

    Posted by Carlos Briceno on Feb 11th 2020

    I recently installed an SXE472 in my truck and ever since, the CAC to Turbo alignment had been off. When I received the RiffRaff billet Plenums, I noticed that they were slightly shorter than the OEM plenums, about 7/16" of an inch shorter. So, once I installed the billet plenums, it also allowed for further rotation of the 472 cover, and this in turn created for the proper alignment of the CAC pipe to Turbo fitment as well. The gasket didn't cooperate much either, so I also had to apply a slight bit of Superglue to keep the gasket in place. I used the glue very lightly, about every 2" or so.

    These things look great. Solid construction and extremely easy to install. Only issue for me, is the only issue for everyone. That one stupid bolt!

    Better than OEM

    Posted by Chris on Jan 21st 2020

    These things are heavy duty and perfect fit. The only thing I had an issue with was one of the oring gaskets wouldn't stay seated in the plenum and had to use a little hairspray to keep it seated while I installed it, but have drove a few thousand miles since then with 0 issues at all. holding boost perfectly.

    Great, but

    Posted by James Turner on Jan 17th 2020

    These plenums look great, perform perfectly, and are a great upgrade! Slight issues to keep in mind are the drivers rear feed line on the Irate RR interferes with the plenum and it must be ground down to clear. Only had to remove about an 1/8" and should not affect the function. Also, the CNC fab HPOP lines have a fitting that must be installed and clocked correctly before installing the plenum. Neither are Clay's fault, so I won't deduct a star for them. Just make sure you do both of those things before torquing the Allen head bolts.
