Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Did an oil change, sticker said the oil was about 4000kms old, was the clearest used oil I have seen.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

1 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 acknowledgements have no verified action link; they do not establish a repair result.

My new to me 2011 cayman base just arrived this week. Bought at auction in Japan and there were no details (got a good enough deal to justify the risk). Mechanical inspection was perfect. Did an oil change, sticker said the oil was about 4000kms old, was the clearest used oil I have seen. Happy so far. Runs and drives perfect. I knew it had custom exhaust , but no idea what. Now that I have been underneath it. Has equal length headers , no cats (thank god I don’t have to pass smog where I live), and a vacuum pump that will open a baffle to basically make it a straight pipe - surprisingly not obscenely loud. Is this pure custom or a kit??? Seems to be very well built. Any guesses? Thanks! James
