All these pipes are made differently, but typically what happens is most of the baffles are lightly welded in place and eventually the weld breaks and the baffle is now spinning around inside the pipe.

You either have to:

1) cut the pipe open and fix the weld

2) get a new side pipe

3) use bigger ear plugs

Sidepipes from another manufacturer are tough, pipes from the same manufacturer are just as tough too depending if that have made chassis changes to the car regarding engine placement.
