How do you secure the 2 pieces of a 3" downpipe?

[VeesGN]

I bought a used 2 piece 3" downpipe and need to know how to secure the curved part to the rest of the pipe. I don't see any evidence of clamp marks.

a 3 inch "band clamp" will probably work.

For mine I used a 3" muffler clamp, I also had to squirt a little muffler cement to reduce a leak I had there, Definately recommend the cement

I installed mine, test fitted it, got everything mocked up just like I wanted it, then marked it, removed it and had the seam welded solid. After the ceramic coating, it looks like a million bucks. Still much cheaper than a THDP. I'll give up that tenth.

3" band clamp, no leaks.
