Brain trust, My 05 spider has developed a bit of a rattle on the drivers side exhaust. It sounds tinny and I can eliminate the rattle by pressing down slightly on the exhaust tips, cat back area, etc. what can cause this and what are the remedies? I have aftermarket headers (not sure of the brand as they are wrapped and were there when I bought her), but stock cat back. I can’t see well enough in the engine bay to see the exhaust brackets or I’m not looking in the correct place. Thanks!
