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 unless proof of sufficient bracing and support to the manifold is provided. Failing to install a flexible coupling on your downpipe will also void any warranty claims. Having photos of the forementioned measures before any failure is a good practice, mailing them to us is also welcome - this will ensure we will promptly proceed with handling any issues that may arise.
