After the intake manifold i have the Europe M3 E36 catalysts, the problem is the part from just before the rear axle to the end, I did bought an M3 E36 rear silencer but it is SO houge ans very heavy so i have to do something else.
To my M52B28 with M50 Manifold I mounted a combination of the catalysts from the E36 328i (metallic catalysts) and the Z3 3.0i rear silencer. The pipe diameters are the same and you just have build an individual solution connection of these two parts (about 50cm of pipe are "missing" between catalysts and rear silencer)
Europe M3 E36 cat merged together with an 323ti sport system, wonderful sound!!

ok, do you mean 2 pipe system all the way? because i got 6 pipe ->2 pipe->1 pipe->rear silcencer with 2 pipe
