Once we saw someone ask "what do I need to do to a OM606 for it to reach 600hp" the common answer was "sell it and get a 648". Not sure if that is true, but due to popular demand we've made a manifold that might help you. - T3 twin scroll outlet for the turbocharger - wastegate outlet with included block plate, gasket and a plate with a hole to weld the V-band flange that came with your wastegate - with high performance in mind, we’ve engineered a durable manifold with smooth transitions and plenty of crossection to make sure backpressure is kept to a minimum. - manifold is test fitted with big turbines like the Garrett gt40 and Holset HX35 in all chassis om648/613 came in with except for the w211. No RHD problems! Please note that warranty claims for cracked manifolds will not be honoured with the lack of a flexible coupling on your downpipe. Using a turbo support/brace is advised on heavy turbochargers like the Holsett Hx35/Hx40.
