By using an increased pipe diameter, stainless steel rear muffler and a valve-controlled setup, Gemballa has created a new sports exhaust system designed to give the Porsche 911 Turbo a more glorious sound.
The previously mentioned rear muffler is compatible with the stock catalytic converters, as well as with the optional Gemballa sports catalysers or the replacement pipes for the catalysers. The tuner will also sell you custom sport pipes with a 90 mm diameter.
If you want to hear exactly what a 911 Turbo sounds like with the Gemballa sports exhaust on, you can do so by clicking this link and playing all those different modes to your heart’s content.
The first two modes are engine starts with the valves both open and closed, followed by full throttle acceleration, half throttle acceleration, full and half throttle passes with up-shift & down-shift as well as 50 km/h (31 mph) runs. Sure enough, all soundbites feature both open and closed valves, not just the engine starts.
