Minimum weight and maximum sound are the name of the game. Our titanium exhaust system consists of our trademark Valvetronic muffler with tips. We use the original actuators to control the valves. Our GT3 / RS titanium exhaust is a super lightweight with only 12.17 kg. That is a weight reduction of 53.1% to the original weight of the stock exhaust with 26.0 kg: a weight saving of phenomenal 13.83 kg. The iPE titanium exhaust offers plenty of advantages. Improved handling thanks to the much lighter rear end of the car, as well as increased performance.
