As tradition, all QD exhaust systems are created using the Modular System concept. QD header-pipes are perfectly interchangeable with the stock muffler, the same QD muffler is perfectly interchangeable with the stock header-pipes. This system allows to use the original exhaust valve. Header-pipes use an expansion chamber system, coming from the off-road world and named BIG-BANG. BIG BANG system helps to increase the torque value immediately available at low revolutions.
