I am not trying to start an e-argument, but there is a benefit of running a huge coffee can muffler on turbo vehicles. More airflow, which helps the turbo breath better, more free flowing exhaust.

It's true, you can run a 3inch exhaust with a normal sized muffler, and still have the same benefits, but some people prefer the coffee can muffler look (I use to drive a WRX). I agree, only Japanese cars should have the coffee can muffler style exhaust, but if someone whom drive a BMW wants that look, let them do what they want, after all, it's there car.
