On the clutch feel I agree with bleeding and maybe draining and replacing the fluid.
Run topgear/soul long tube catless headers into the milltek muffler

Milltek is a great muffler and you can run Topgear/Soul long tube catless headers into the Milltek muffler for a great sound that does not have a drone.
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.

Hi there ,i’m from italy and i bought a
Cayman
987.1
s with two little problems to solve:
1) an exhaust rattle Coming from valve in the muffare, i Think i have to change mufflers
i m looking for some not exspensive and not much loud
milltek? Is that too much loud?
Topgear uk? Are they good manufacture?
Soul? I can’t find it in europe
2) the car has 70k km and the pedal of clutch is so hard, not slip or tear, only hard pedal.
could be have to change clutch? May be something other?
Thank yo for your suggestion
i do it by myself.
sorry for my english
great forum this

Milltek is a great muffler and you can run Topgear/Soul long tube catless headers into the Milltek muffler for a great sound that does not have a drone. I would just get used to the clutch! The heavy clutch keeps the clutch disk from spinning and causing flywheel damage. Enjoy your new toy.
By the way the Milltek muffler stainless steel shines beautifully through the rear air way.
Izzio, where does the clutch engage / grab? Near the floor or almost the top of the release? Have you experienced any slippage, especially on inclines? If it's never had a clutch and depending on the shifting habits of the PO it could need a clutch job at that mileage. You can always try bleeding it as an inexpensive first approach.
Izzio, please expand your description of where the clutch engages. No clutch slip, like Boris mentioned especially starting up hill, would give a good idea how the clutch disk is functioning. I changed the clutch at 48k using a Sacks clutch kit, in January when I had the Wavetrac LSD installed. I thought the clutch was pretty much toast. But to my surprise about 40% or more was left on the disk face including no marks on the flywheel face. Too bad, as I should have went with a lightweight flywheel to get off the starting line and blip the throttle in downshifting.
For what it’s worth, I have the Soul competition exhaust. I personally love the sound, there is no drone and doesn’t sound like a fart can Japanese car. If you only do mufflers and keep cats it would probably be what you’re looking for. On the clutch feel I agree with bleeding and maybe draining and replacing the fluid. Since you have a standard, another thing to anticipate is your shifter cables snapping. Mine did and luckily it was a block from my house. I replaced with Numatic cables and got the shifter to match. It’s a much better feel and worth the coin.
The clutch is hydraulic, so maybe change that oil? "Hard" pedal is pretty subjective. I don't think my 2008 CS is particularly hard, but maybe I've gotten used to it.
Thank you so much, so i study the muffler rattle ad it become from depression valve, it moves inside, if i press sport button rattle disappear.
clutch , another

Thank you so much

Hi, finally this morning i take some time trying to solve the rattle problem.
so, seems like not enough vacuum for pull strong the valve but when you turn off the engine ,for a few second vacuum is on and the valve stays strong pulled on close . So i desume no leaks of vacuum.
i suppose something like ecu at idle not to command maximum vacuum, is it possible?
Take a look at this video, thank you for suggestions
i can t upload video
