correct muffler?

[porsche356]

Hi,

I am replacing the mufflers (not sure whether this is the right word) of my carrera S. The number of the muffler under my car is slightlt different than the ones I have bought. I currently have (right side): 997/11, 997 111 311 04

The new one has : 997/11, 997 111 311 03. Is this the right one for my carrera S? Or did they sell me the carrera ones (because the 04 in the end is now a 04)?

Thanks, frank

Those are sub-assembly numbers - what is the part number on your invoice?

Hi Loren,

I did not buy these at the dealer. Invoice only says carrera S exhaust. Because the number is different then what is currently under the car I am in doubt whether I have the correct one.

Is there a number on the muffler I can look for?

On the 996 mufflers there were both part numbers and assembly numbers. The real part number was usually next to the Porsche logo (triangle with a P inside).

Thanks Loren, I will check it tomorrow.

Are the diameters of the pipes equal for both the carrera and the S??

Sorry, I do not know. Have not had a chance to compare them yet.

I've seen both 997 and 996 exhausts next to each other, and the tube widths are identical
