Solid!
This clamp set is a clean, no-weld solution for exhaust enthusiasts looking to keep their builds tight and tidy. Made from 304 stainless steel, it’s corrosion-resistant and built to last—even under high-heat, high-vibration conditions. The 3.0-inch butt joint design means it’s ideal for joining pipes, mufflers, or catalytic converters with matching outer diameters, delivering an even 360° seal that minimizes leaks.Installation is straightforward: just slide the pipes into the sleeve and tighten the bolts—no torch, welding, or hassle. The I-block and reaction block system ensures even clamping pressure without distorting the pipe ends.Whether you’re doing a full custom exhaust or patching in a component, this set offers a secure, sleek alternative to bulky clamps or messy welds.

Great easy fix clamp
Exhaust fell off after a bad pot hole 🕳️ cops made me fix it said my car was quote “to loud for public roads” maybe they should fix their d*** road so I don’t have my exhaust pipe ripped off!! This little thing works great and is easy to install definitely something ild recommend for a easy break on your exhaust on your car

Does exactly what it says!
Did exactly what I needed it to do! I had replaced a flex joint up stream in the exhaust and it ended up being an inch to long - this let me easily take an inch out of my exhaust and quickly put it back to gether.

Good product if you order the right size lol
I ordered the wrong size. But I'm keeping them because you never know. They feel really durable. I like the design. The size is absolutely what they describe it as. And they're quick to install.

Good temporary fix for broken exhaust
Worked as a good temporary fix to hold my exhaust together and make it less loud until I could get it fixed correctly.
