Surprisingly result comparing with stock engine.
Better torque, Faster response and additional driving experience.
Anyone know is there any other tuning parts for BMW 520i N20 engine? (Besides: Exhaust. )

Thanks for sharing. I've also got a 520i and have been wondering whether the ER downpipe is compatible with 520i.
I think you would probably want to look for an intercooler upgrade as a next step, although AFAIK there is none commercially available yet.
