Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

When I bought my 99 C4 the dealer said that the car had the motor sound package. I was trying to figure out what that was but could not find anything. Is it possible that he is talking about PSE being installed? If so how can you identify if the PSE is installed. The car is pretty loud but I haven't heard any other 911 recently to compare. Thanks all Bobby

POST 2Original post

Normally, PSE is installed with a dash switch. Also, the PSE isn't loud per se. Its just sweeter and more raunchy when you pound it. Could it be the Bose system he is talking about? DO you have some sort of extra audio package?

POST 3 / ORIGINAL POSTEROriginal post

He said I had the HiFi package but then said it was equipped with the motor sound package as well. I know the 993's had this option but not sure what that is on the 996 or if he is just plain mistaken. Thanks Bobby

POST 4Original post

I don't think PSE was available as a factory option in MY99. Did you buy it used? Maybe they installed PSE or an aftermarket exhaust after it was purchased new.

POST 5Original post

Is there a clearly identifying mark/feature on PSE vs stock?

POST 6Original post

I have a friend with a 993 turbo, with the motor sound package. It means you have an upgraded exhaust system, possibly the PSE or its predecessor.

POST 7Original post

Motor sound package was to the 993 what PSE is to the 996. So, yes, he was talking about an upgraded exhaust sound, calling it the motor sound package out of habit from the 993 days. Early PSE had NO switches. You should be able to confirm it with the option list.

POST 8 / ORIGINAL POSTEROriginal post

Is there any way to look at the exhaust and confirm that it is the PSE through some markings or other. Where is the options list? I misplaced the window sticker but is the list somewhere on the car.

POST 9Original post

There's an option sticker on the inside of your trunk lid, near the front. Also should be one on the first few pages of the maintenance manual. This is what the newer generation ('02 onward, I believe) mufflers look like. You can see the bypass flaps just to the left and right of the www.carnewal.com. The first generation mufflers have much smaller bypass pipes:
