You can't just yank off your 35i tips and slap on the 50i. You'll need the 50i pipes.
There are two problems you will run into 1) the openings through the bumper on the 35i aren't large enough for the 50i pipes. You'll have to bore them out. 2) the 35i has a valve on one side of the car that keeps one side closed except during high pressure. Keeping both sides open will noticeably alter the sound of the i6 exhaust. Some people also complain of a loss of low end torque, but theoretically it shouldn't affect a FI engine... at least not to my understanding.

Can you explain what is the function of the valve? If it does not affect a FI engine then why they design to have a valve there? For X6M there is also valve there. Don,t tell me to lower the noise of the exhaust!
