but i hear abotu HP gains and torque etc, but is there any real proof? it seems tough for me to pay $2000 US + for a HP/TQ gain that isn't even documented anywhere.
If you guys can point me the right way, I will greatly appreciate it

You really aren't going to see a huge gain from an Eisenmann exhaust on a 528i. Especially since the exhaust is only a muffler. You may see a 2-5 peak horsepower gain, but the main difference is sound.
If you are looking for a power bump, go with the BMS powerbox. Will give you a nice little 10hp kick, and improve throttle response and driveability.
