Due to the 76 mm Downpipe completely without catalytic converter, the back pressure is significantly reduced and the turbo is relieved. This brings more power and less exhaust gas temperature. By retaining the original flanges and connections, the downpipes fit perfectly and without modifications to the turbos. So that the heat also remains where it should, we have the downpipes still thermo-insulated.
