exhaust vibration & how do i make my car quieter ?

Recommended Posts

i'm new to this forum and forums in general and am looking for some advice. my RS has recently developed an exhaust vibration / rattle. it seems like an internal baffle issue and was wondering has anyone experienced this. i would take to the main dealer as still under warranty although this means i would have to remove the upgraded brakes etc as we all know what porsche are like with aftermarket parts .

Anyone come across this...help ??

i would also like to get the car under 101db ....how do i do this as it currently struggles to get under 105 !!

The brakes should have nothing to do with the exhaust rattle under warranty unless the exhaust has been altered.

Could be as simple as a heat shield that has been bent or a loose bracket. Or a defective (broken internal weld) muffler.

You can always look around under the car for the heat shield issue or loose brackets.

ok thanks for this. you hear so many horror stories of porsche centres invalidating warranties due to wrong fitment of batteries and tyres, i was worried the brakes would do the same. i tend to agree its likely to be a heat shield or similar . thanks again

I have had some ugly rattles/whistles from my Porsche Sport Exhaust, and asked the dealer to look into it several times already. All they did was tighten up some of the brackets, but the sound remained. Today, I was back there, and had the car on a lift, and we noticed 3 cracked welds on some of the brackets (left and right, near the tips, and one on the central bracket). Porsche ordered the central bracket, and once received will install this and reweld the 2 other trouble spots. I will report again when this is done. I'm very happy the root of the problem has been identified, and am looking forward to hearing the growl without the rattle. Hopefully this won't cost me an arm and leg...

Update (late): The bracket was repaired and spot welds made to L/R brackets...and the exhaust is rattle free.
