Schmiedmann E39 High Flow Sport Manifold M52/M54 Inclusive 400cell Euro3D4 Sport Catalysts (Does Also Fit RHD Drive Models)
Guiding mount time:6,5-7,5hour(s).
Please note: The system is not E-marked!
Complete set inclusive sport catalysts! Some adjustments can be necessary in order to install the system!
Please note: Does also fit RHD models, all you need to do is making a very small dent in the manifold - and to modify a heat shield a little like shown on the pictures!
IMPORTANT: We haven´t tested the system, on models year 09/98- with the 4 oxygen sensors and catalyst in the exhaust manifold! if the oxygen sensor wires are not long enough, then try to take them out of the holders, and place them behind the engine over the transmission! please call us if you have problems!
This is one of the most effective ways to gain more power on a 6cyl. E39 gasoline model. This manifold inclusive a sport endmuffler increases the power on a E39 530I with approximately +20HP, and brings the max torque up with additional 37NM!. The system makes the car louder, so we recommend to install a sport endmuffler that isn´t to loud!
