Super lame.
Care to explain the "general reason" cars have multiple exhaust exits?

E36 M3 and E34 M5 both have dual tip exhausts from 6 cyl engines
E46 M3 have quad tip exhaust from 6 cyl engine

E60 4 cyl engines have single tip (oval) exhaust
F10 4 cyl engines have dual tip exhaust

The following pictures shows different cars that all have a double exhaust system, independently of engine configuration (V or Inline - 4 or 6 cyl).

E36 M3 exhaust system:



E46 M3 exhaust system:



E30 M3 exhaust system (4 cyl engine):



Ford Sierra Cosworth (2l Turbo 4cyl engine):



Koenigsegg have just one exhaust outlet:



4 cylinder cars with multiple exhaust tips:

Vauxhall Astra VXR (2l Turbo):



Golf GTI (2l Turbo 4 cyl):



Passat Alltrack (2l Diesel):



Ford Mondeo TDCi (2l Diesel):



As far as I can see, multiple exhaust tips are used mostly for appearance, and in some cases to get enough flow capacity.

In the future I suspect we will see 4 cyl M cars again (E30 M3 was 4 cyl) and I won't bet against them having the now mandatory quad exhaust tip.
