Re: Porsche Sport Exhaust "loudness" modification - warning
easy_rider911 said : IMO the reason why the vacuum hose method may have been described as 'dangerous' to Adam2S is because people may not cover the ends with tape well enough to prevent a problem developing.
Yes easy_rider911, thats right. The problem Andreas had with the vaccum hose method is that if the vaccum system wasnt properly sealed again once disconnected that it could lead to damage elsewhere, he said that even if it was intially sealed there is a risk the seal will subsequently fail but this cannot happen with the brown plug method. The brown plug method was therefore the only totally safe option. Both achived the same result, but one was risky and the other wasnt therefore he would only recommended the brown plug method.
John H said : Woah woah - hold your horses... you can't suddenly come up with a statement that definitive and that totally conclusive..
These comments are not mine - they are direct from the mouth of Andreas Preuninger who is the head of GT car development for Porsche. This man clearly knows far far more than any dealer or technician in your our dealership. Andreas clearly demonstrated his vast technical knowledge of the cars on all areas, he talked about many many technical aspects of the car in great and minute detail. This is the first time Ive heard something this definitive from such a credable source. Also this is not a second hand quote, I and several other customers at the UK GT3 event heard it first hand with our very own ears. There was absolutely no doubt about what he said. In my mind is as conclusive as I think it could ever be!?
So he wasnt saying the vaccum method wont work, far from it he said both systems will work, and both if done properly are ok. This is big news in itself as it removes the whole doubt if either method at all was a good idea - Ive heard of dealers telling people that the change in back pressure could damage the engine, clearly this is wrong, Andreas said it is safe to disable the baffles as long as it is done correctly.
It is just that he said one method is risky (but obviously it can work fine for many people), the other method has no risks whatsoever. I know which I will be doing on the next car
