🔧 SmartParts 300300 3" Lap Joint Preformed Stainless Steel Exhaust Clamp with I Block: Efficient and Durable Solution Review

As expected. Used on a 94hp car with a 3" exhaust. I put it on double glazing and there were no problems. Would order again.

I have these to seal the manifolds on my manifolds where they meet the exhaust pipes. They look great and feel like a quality product. No more leaky headers!

This clamp is carefully polished stainless steel and is the right size to create a good seal between the flexible hose and the pipe in my exhaust line. Good looks at a good price.

Doesn't provide enough clamping force, probably partly due to poor/poor fitting of my exhaust kit on ebay. I twisted these clamps until they failed and I didn't even get close to sealing the exhaust. I've had similar results with other brands of clamps that were a similar style, suggesting a pipe could be to blame. If I ever do it again I'll just put it on a jack and weld it.

As good as a stainless steel clamp. These are the first "preformed" ones I've used and I find that preformed is an advantage when it comes to creating a tight bond between components. Band clamps are best because they don't compress or deform tubing like U-clamps do. They hold up just as well as a weld, so the connection can be broken days or years later without damaging a component.
