Porsche 911 966 has always sounded a bit tame. Yea it has 3.4-litre flat six engine but the stock mufflers are too… stock.
There are numerous ways to make your Porsche sound awesome and one of those ways is of course with expensive aftermarket back box but… there is a way you can do this very cheap and probably with better results!
All you have to do is weld a small bypass pipe between the inlet and outlet pipes which allows some of the exhaust gases to bypass the sound deadening muffler. This will change the sound the tone and the volume of the car. Important thing to know is that this mod will make your exhaust permanently in sport mode.
Watch the modification being carried out and compare the sound of the car before and after this “hack” in the video on the next page.
