It just seems that my engine likes to rev pretty quickly, and with the flat torque curve, and the relatively high "max" speed we enjoy, I thought these are usually signs of a "good breathing" engine.
what i know is the slk320 and the slk32 use the same exhaust manifolds... that does not sound so good to me... I am not sure if this applies to us but I would not be surprised if it does...
they had to cut costs somehow and this was just one of the ways... and they did not bother recreating a new exhaust manifold for such a low production car... as the slk32 also has no more than 3,000 produced... even fewer than the srt-6.
the problem with n/a engines is getting enough fuel running through and the problem with forced induction engine is getting the gasses out so I am sure that this point can be improved on especially if you were to do other modifications like increasing the psi... besides the stock exhaust has to pass emissions, but an ideal one does not...
