Review on HPS Stainless Steel T-Bolt Hose Clamp - Size #68, suitable for 2.75-inch ID hose, Range: 3.00 to 3.31 inches by Dave Lopez

I believe these clamps are for rubber hoses, coolant hoses or inlet hoses. I saw them used on a motorcycle exhaust and decided to try them on my car exhaust. They don't have the ability to pinch enough to pinch the exhaust pipe, so slits must be cut in the outer pipe. In my case, the slots were pre-cut into the tube at the factory. These clamps provided enough clamping force to hold the slotted outer tube securely against the inner tube in my exhaust system. They look a lot better than regular exhaust clamps and don't deform the pipes so they can be disassembled in the future.
