Devised and developed for the 2009 Motorally championship.
Non-homologated, the QD exhaust modular system manifolds are perfectly interchangeable with the original manifolds and, though they are ideally completed with the aluminium â€" or titanium - QD exhaust, they can be mounted together with the original exhaust pipe, as well.
QD manifolds are the outcome of many years of racing experience, and can be considered among the most highly performing, high-tech exhaust plants for the new BMW Twin. Great torque and homogeneous power during the whole length of delivery, are the features of the new manifolds, made for the F800GS. Peak horsepower comes on earlier, and peak torque is up near 4 ft lbs.
When you adopt these manifolds, the whole exhaust plant will no longer be homologated for use on road because of the elimination of the catalytic converter. In any case, the substitution may turn out to be indispensable should you undertake travels to countries when the availability of proper petrol is not ensured. Moreover, the increase in power over the whole arc of delivery can be helpful if you foresee undertaking travels with full load.
