Review on SmartParts 320300 3-Inch Butt 🔧 Joint Stainless Steel Exhaust Clamp with I-Block by Paarvin Freedman

So far so good. I was a little worried about the lack of detailed instructions. Nothing says how the unit will be installed, it simply comes pre-assembled for easy installation. I always like to double check these things as the block is not symmetrical at the top and bottom. In the end I just trusted the company to put it together correctly and installed it as is (smooth radius on bottom closest to pipe, sharp edge from pipe). tightened to 55 lb/ft. It stayed on the first drive, will be updated if there are problems.
