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.

If your going to do anything with the up-pipes just order these and have them on hand before you start. Even with soaking in penetrating oil and a bit of heat from torch still had to cut both passenger side bolts off and one of the drivers side twisted in half while trying to remove it. SAVE THE HEADACHES just cut the old ones and put in new.

These are in the 99-03 section but fit the earlier 7.3's as well. Order these in advance of starting any up-pipe work and save yourself a ton of time and frustration. Removal of exhaust hardware is always tricky. Just cut it all off and replace it.Even if its bolted on and you round the bolt heads,you can grind off the head and get the part off ( y collector). once its on the bench,you can soak it, tack a nut on the bolt,and remove it way easier than under the truck. New hardware goes back on way easier too. These bolts are factory fit so it's a job done right at minimal cost. Buy the bolts FIRST, then start the job!
