Evrything i get from you guys has been top notch! Never have i gotten anything below awesome!

The price was the best for top quality parts and I got it fast!

Great kit. Got the bolts too. Replaced these when I rebuilt EBPV. Up pipe were black but I couldn't see it from up top. After it was buttoned up, I gained 10 psi on the top end and quicker spool up. Great kit if bellowed pipes are not in the budget.

Perfect fit, made for an easy repair.

These black oxide bolts are really great when your OEM up-pipe bolts are rusted solid to the exhaust manifolds. So glad RiffRaff offers stuff like this instead of having to find stuff that fits from a hardware or bigbox store.

Don't waste your time trying to re-use the old hardware. The old hardware will snap very easily. Use new hardware and never worry about it again.

I have ordered many Riff Raff products and everyone has been excellent. This kit was no exception. Replacing up pipes on a 7.3 is absolutely no fun and you don't want to reuse the original bolts and find out halfway through that one breaks. Mine were 17 years old and had rusted so bad I couldn't put tools on them. Anytime I've had a question Clay has answered quickly and accurately. I'm always glad to do business with Riff Raff.

This hardware is exactly what I needed to fix my leaky factory OBS uppipes. If your doing new donut gaskets like I did I recommend you getting this bokt kit. The old uppipe bolts get very brittle from years of heat cycles, and they tend to snap very easy. My advice is a couple days of WD40 or PB blaster and heat cycles for removing the old bolts. You want to avoid breaking them off in the collector/babies butt because they are harder than a grade 8 bolt and there's no tapping the broken bolts out, resulting in you buying a new $150 collector/babies butt

More convenient for the price than cleaning and inspecting hardware.
