I have a 2001 boxster with 100,000 miles on it. I have noticed a rattle the last 1000 miles which appears to be coming from the right side warm-up catalytic converter. I mostly here it when a low rpm's. I noticed it gets louder when the engine is warmed up to normal operating temps. It sometimes seams to be accompanied by an exhaust leak type noise when I let up on the gas. Any ideas of what this could be would be greatly appreciated.
