EVIL ENERGY 3.0 Inch Exhaust Clamp,Narrow Band Muffler Clamp Stainless Steel for Pipes,Mufflers,Catalytic Converters 2PCS

They did the job

I needed to attach two 2.5" pieces of exhaust under my 1981 GMC Sierra 1500 pickup. They made it easy to do and since I had no way to weld them together, it was a good deal for me.

Speedy delivery and great quality

I've used this style of band clamp on motorcycle exhaust before, since you have to take the mufflers off to be able to remove the rear axle for tire changes. I have always used the U-bolt style clamps for cars and trucks, since you hardly ever have to take them apart unless replacing the exhaust or something major has gone wrong. I decided to try these and they worked really well for the piece that fit tightly together. I did end up using a U-bolt style on one connection since there was a tiny gap.

Well build

Works just like it's supposed to. Used on a 1998 Roadking

great clamp. fits on a straight 2.5" or a lap joint 2.5.

Keypoint: The hardware the use on this impressed the hell out of me! I'm very familiar with working on cars and the force I needed to use to get my slip join to actually clamp I thought for sure the bolt would snap or the splined part strip. It did not and everything is holding together great will update if it rusts out or something else bad happens long term. There is more details about my use below.These clamps design don't allow them to fit a lot of the variances in exhaust piping so fitment/sizing can be frustrating. I was using these to clamp down on a stainless exhaust slip joint with no relief slots cut in. This is an example where this clamps inability to cover a wider range of diameter makes it a pain. The 2.25" pipe expanded to make a slip joint is slightly too big for the 2.25" clamp for the sizes they list and too small for the 2.5" clamp. I took the risk I would be able to take the clamp apart get just enough of the threads to get it started and make it work.This is how it worked out I had plenty of threads to get it started but I was not expecting the amount of torque I would need to apply to get the slip-on joint to clamp down. I'm not sure if it was the stainless slip joint having no reliefs cut into it but the amount of torque I had to apply to the nut to get the joint to lock was a ton for an exhaust clamp. The fact the bolt did not snap or the spline part strip is a credit to this product.
