Cayman S exhaust flange bolts size

Recommended Posts

Hello 

I had my 2009 S PDK inspected by the local dealer today and whilst on the ramp they showed me the three bolts that hold the two parts of the exhaust were rusty , they want over £500 to change these (exhaust flange triangle bolts and gaskets corroded is what it says in the report )  Can anyone tell me what size the bolts are and where I could get them in stainless steel , and where to get the flanges  please 
cheers

The dealer should sell you the bolts at the parts desk for a few quid. The job is an absolute pig to do though even with the right air/power tools.

I can confirm through personal experience that this is a pig of a job at home with the car on axle stands and without an oxy acetylene torch!  So when our other Cayman needed a clutch recently, I got my local OPC to do it this time. 

 

Our TIPEC region has a very good deal with our OPC so the labour cost was £460 to change the clutch and deal with the corroded exhaust studs in the process.  They even let us supply the clutch kit and exhaust clamps and stainless bolts.  

 

So £500 is way over the top.

The bolts I used on both our gen 1 Caymans were bought from ebay:

I used the M8 x 30mm ones, along with stainless nuts with integral washers:

You also need to replace the gasket between the two flanges but not the flanges themselves as these are an integral part of manifolds and exhaust system.

Your nearest OPC should be able to post them, or else I suggest Design911 for the gaskets.

I paid £440 at a well known Porsche Indy to have my exhausts changed.  Car was just 2.5 years old and kept in the garage.  It took them hours!!

would it not be cheaper and beneficial to run over to Carnewal in Belgium and get Gert to put one of his modified exhausts on including new bolts and gaskets which is likely to cost less than your local OPC just changing the bolts and you end up with a sporty exhaust .

I had the gaskets go on my 07 S and the bolts were rusted in to the manifold. I took it to a local race engine specialist who had it for a couple of days. It is right it is a pig of a job to have done, but they did it for £270 for one side.
