Looks like both mufflers are very interchangeable and used the same mounting hardware and brackets.

I need to replace my Miltek exhaust system from my 06CS (85k mi) and want something that still sounds as good and no drone.

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

Hello All, I removed the Circuit Werks stainless muffler from my new-to-me 2006 Cayman S (stainless muffler and over-the-axle side pipes) and replaced it with a stock muffler. It was in great shape, just a little too loud for me. Looks like both mufflers are very interchangeable and used the same mounting hardware and brackets. Can someone who is more knowledgeable about exhaust systems tell me what models this Circuit Werks muffler would fit on? Would it fit on both the 987.1 and .2 Cayman and Boxsters? I keep getting questions from people asking if it would fit on their Boxster , or 987.2 Cayman , and I simply don't know. Thanks much, Steve

POST 2Original post

Just a thought...I also had an 06 S with CircuitWorks exhaust, and wanted suggestions how to eliminate drone. I called them and the fellow who answered must have been one of very few people who worked there, because he was technically very knowledgeable at a ground level (not a desk jockey salesman). So, maybe just call them directly and ask?

POST 3Original post

This isnt complicated. A 15 second visit to the Circuit Werks website clearly says they fit both Boxster and Cayman models. The 987.2 version for 09-12 is a completely different item/part number from the 987.1 so again, the info you or they are asking for is right there on their website! 05-08 Porsche Boxster & Cayman 987 V2 Catback Exhaust 987.1 S 2005-2008 Porsche Boxster & Cayman 987 (AKA 987.1) V2 Dual Muffler Exhaust System w/ Dual 3.5" Thick Wall Tips.

So what was their solution for helping with the drone? Are you happy with Circuit Works exhaust and a good performance sound? I need to replace my Miltek exhaust system from my 06CS (85k mi) and want something that still sounds as good and no drone. Thx
