Trying to narrow down a loud rattle issue when I start my 95 Suburbun. Sounds like metal on metal for about 10 minutes till it gets warm. After that, it runs like a champ. Has about 127500 on it. Thinking its the catalytic converter but never have encountered one that quits the noise after it starts. Any ideas will help. Thanks
