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.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

POST 1Original post

Are the 3.8L headers the same as the headers used on the 3.4L cayman ?

POST 2Original post

Looking up the part numbers for both would probably determine whether the answer is yes or no.

POST 3Original post

No they are different. Neil

POST 4Original post

Neil! Way to go monitoring the site. If you aren't careful you may end up with some business. Thanks for your technical expertise.

POST 5Original post

Neil, I have a question here. I know that the factory headers are different for the Cayman and 3.8 997 because the exhaust systems are different. However, the 3.8L engine and the 3.4L engine have the same engine heads and block, only the internal bore is different. Why would this require headers being different for the Cayman if you tossed in a 3.8L motor? Is the motor sitting in the car differently for some reason???

POST 6Original post

<p class="MsoNormal" style="MARGIN: 0in 0in 0pt">The primary tubes and the ports are the same size 3.4 Cayman & 3.8 S even the exhaust flanges are the same size. The difference is that the flanges are not in the same place where they bolt up to the rest of the exhaust. In theory you could use the 3.8 S headers but you would then have to fabricate the rest of the exhaust system<o ></o >[/quote]

POST 7Original post

Neill, I get what you are saying in terms of the FACTORY headers being different from the Cayman vs. 997, as your pic shows the 997 is on the left, the Cayman is on the right. What I was asking is that if you fabricate a set of headers for the 3.4L Cayman , that you SHOULD be able to dump in a 3.8L engine into the Cayman and use the SAME headers. I was not suggesting that you could use the 3.4L Cayman headers in the 997. Am I making sense now? In essence if you have a set of headers for the Cayman it doesn't matter what engine is in the Cayman , the 3.4, 3.6 or 3.8, the header still work because they are fabricated for the Cayman correct?

POST 8Original post

Ken you are correct.If you fabricated a set of headers for the 3.4 Cayman and then later dropped a 3.8 in yes you could use the same headers. Neil
