I'm wondering what this 4-cylinder would sound like if you put a BMW Performance Exhaust on it.

Exhaust system design can only do so much. Ultimately, the firing order and number of cylinders determines the harmonics that give each cylinder layout its unique tone. If you put BMW Performance Exhaust on the N20, it's still going to sound like a 4-cylinder.
That said, a 4-cylinder doesn't have to sound like a riced out Honda. Have a listen to the E30 M3 for a great example of a kick ass four banger exhaust note.
