IF he is running his return pump wide open at the moment that's all the flow he will ever get out of that pump. If the drain is noisy that's a seperate issue that's needs to be addressed by a solution other then placing a valve on the drain.

Running a valve on the drain is a very dangerous way to regulate flow or noise, snail goes down his drain = flood, valves starts to gather crap, clumps of algae = flood, fish goes down the drain = flood, and it will happen eventually. It's always best to regulate flow on the return side.
