Hi,

I have benn a big unregistered follower of the forum...but now I seek your views on this issue:
I saw this when the car was lifted up....the mechanic says there is nothing to worry about..but I want a second opinion just in case..

I can't see from the pic what your worries are?

The only issues that I know normally with a bad exhaust, is that these cars can lose power with the cat removed, or doing aftermarket exhausts that are not designed as well as the original.

Sorry I meant the carbon build around the sleeves clamps

That means its leaking.

So is it something bad? My mechanic seemed not bothered with it so I need to check wether I live with it or change my mechanic...

I have slithered around under my car a bunch but I have never noticed a clamp type connection except for the tip.

oh I think I posed in the wrong place! this is a cayenne 2008 GTS...sorry for that!

Well that makes more sense

They really do need to break the cayenne board into more than one.

At this point the cayenne models are Gen1 955/957 Gen 2 958

Only confusion I usually see with the 968 is the 986, which is the boxster.

But yes, that is a leak and should be addressed.

The good news here is that everyone is correct. Yes, it is a leak, but only condensation weeping past the clamp which is not design to be a watertight seal. Your technician is also correct - unless there is audible noise, forget it. Over half of the cars that we service with that style of clamp looks exactly like yours after a few years.

Also in your pic it appears that the split in the clamp is pointed down. This is allowing the condensation an easy way out. If you want to get real crazy you can remove the clamp, wire brush the inside of the clamp, the outside of the exhaust pipe, reposition the split somewhat upwards and coat the pipe with exhaust sealer.

But I wouldn't do such to mine.....
