Review on Efficient Walker Exhaust 35414 Exhaust Clamp for High-Quality Exhaust Systems by Jason Winkfield

Well basically this product is cheap, the nuts aren't big enough to fit properly on the yoke. The nuts get to a point where you can't tighten them because they start to bind. If the nut were bigger it would sit properly on the clamp so you could tighten it enough to actually close the exhaust pipe, but you can't get the pipe to never close. The threads on the Ubolt are weak, even if you could caulk the tube the threads wouldn't withstand the ft-lbs required to caulk. All in all, save yourself a lot of headaches and buy a stronger clamp. I've ordered some of the jegs and the difference in grip strength isn't even a contest. The collar is the same type but the ones I got from Jegs are much stronger. Don't waste your money and time with these cheap clips.
