One V clamp and donut gasket for each cat to manifold joint. Then a clamp for the left cat to the Y pipe. Bolt and springs with donut for the right cat to Y pipe. That gets the Y pipe to engine side. Then donut gasket and springs and nuts for the muffler to Y pipe, and a clamp for the muffler to tail pipe. Those are the good clamps. The nice thing with them is they don't crush the pipes and cause issues if you need to take things apart in the future, and you can just snug them up as you put the system together until you get all the pieces into the hangers and position. I normally do the engine side first, then hang the tailpipe and slide the muffler into it with a snug clamp. Then couple the muffler to the front pipes.
Adjust it all to get things into position and start snugging the clamps up, then once it's all in, torque the clamps down good. If there is any doubt that a joint could leak you can apply a bit of the exhaust paste they sell as a sealer.
