The noise you hear from rally cars is anti lag and external wastegates.

Rally cars have antilag which keeps the turbo spinning. Yeah they're getting flutter from the air going backwards through the turbo, but it doesn't matter.
On the case of a normal car a dump valve reduces the strain on the turbo during turbo stall. They can however dump off too much, which means all the charge pipes need recompressing. If they dump off too little then the turbo shaft is still under strain. Manufacturers opt for recirc setups which make sense from a noise and emissions perspective. Personally I think dump valves are gay and should only be used on high pressure systems and preferably recirc too.
