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 F82 M4/F80 M3 titanium exhaust is a super lightweight with only 13.07 kg. That is a weight reduction of 40% to the original weight of the stock exhaust with 32.28 kg: a weight saving of phenomenal 13.07 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.
