Italian tuner Romeo Ferraris this time has tried its hands on a German car, the Porsche 997 Turbo.

They have boosted the performance of this supercar by 70-hp, using sport air filters, new ECU mapping and sport exhausts.

The exhausts are the main highlight of this 911 Turbo. Romeo offers different systems for the car, with the top two being from Cargraphic and Akrapovic. The Cargraphic system is made of stainless steel and has active valves in it, which means they are quiet at low rpm, but at high rpm as the valves flick open it barks like a wounded dog.

The Akrapovic system is by far the superior, made from titanium for lightness. It still makes a great noise, but because of its weight it also contributes to the car’s performance. They are more expensive though.
