Recently I heard a buzzing from my exhaust when the engine is coming down from high rpm. I took off the exhaust to see what was buzzing and I shook the resonator which is located right before the cat and I heard something loose inside of it.

The buzzing is really bothering me. Can anyone suggest anything that I can do about this? Is the resonator ruined? If it is, what are my options in fixing it? Do I have to buy another one from HKS or could I get an exhaust shop to weld on a new resonator? Also would the new resonator change the sound of the exhaust? I love the sound of the HKS and I do not want top change it.

Any suggestion would be much appreciated. Thanks
