That looks like an m50 to me, they do a 2.0 m50 150bhp and m52 2.0 150bhp the m50 2.5 is around 192 bhp
the m52 is the 323 whch is a 2.5 170bhp and 328i whih is 193 bhp
pretty sure this is correct
That's an M50
So tuning wise is there anything I can do to add to the decat and cone filter?
The guy I bought it off mentioned it had some sort of exhaust manifold which was a good one, I don't mean a stainless aftermarket one, a genuine one? I suppose I should try and get a piccy of that
