The Tubi Style GT3 Three Pipe System features three uniquely designed tips that each have a very specific function under various driving conditions. The center tip is the main exhaust outlet when the sport valves are closed, while the other two tips are dedicated to relieving the increased flow that occurs in Sport mode when the exhaust valves are open. The result of this unconventional design is not only a very unique look, but a noticable improvement in performance and most importantly, sound.
