Hey Porsche Community, I'm seeking input please. My 2011 Cayenne Turbo's muffler has developed a nasty rattle, not RPM dependent, it sounds like one or more of the baffles have come loose internally and are rattling around. As this is a sealed unit, I'm seeking any expertise or advice to confirm a new muffler is needed before plunking down $2k (rough minimum) to replace her, and are there any concerns about driving it this way while I figure this out. Any input would be appreciated, thanks in advance.

 

if you can isolate roughly where the noise is coming from you can probably have a muffler shop cut open the muffler, repair the loose pipe and weld it shut again. Alternatively, maybe post a WTB ad for a used one where someone has upgraded theirs.

 

Thanks, that's great advice.

 

I have my stock one but it is HEAVY and large. Would probably be very spendy to ship. I'd check with a good local shop first. Or just rip it off and put some aftermarket mufflers in there.

 

As a point of information, I shipped my OEM Turbo S muffler from SC to MA using Greyhound freight for $93

 

Thanks for the shipping reference cost.

 

Good advice on seeking a local shop.
Regarding your stock one, would you be willing to sell it if I pay the shipping?
Thanks,

Honestly? Probably not just because I don't want to go through the hassle of packaging it up and getting it to a Greyhound place (the closest one to me is probably 50 miles away or so). Mine is a 2005 for one thing so I'm not even sure it would fit yours.


If you absolutely don't come up with another solution let me know and I'll see.

 

Understood, thanks

 

I never say never though. Did you find anything out yet?
