Instead of being a straight bypass pipe has a small resonator chamber which cuts the noise down some as opposed to the straight through pipes like Dansk, Schnell or RUF. This would allow you to use a G-Pipe while not being too loud and lose the Secondary Muffler on the car so the neighbors would not complain. This was on my car for about four years and on trade-in the dealer wanted it stock. So I did return it to stock and am now selling off bits and peces that I can not use on my 993.


This is an easy upgrade that loses weight in the back and makes the car sound beefier.

But sound was amazing ❤️❤️❤️
