^ I wouldn't be so quick to assume that becuase someone else likes the tone and sound of a different exhaust system, that they are blinded by the name brand of that system.
You're happy with your system, and others are happy with the system they've purchased, albeit at a much higher price. It's not your place (nor Wall$street's) as to whether those individuals are fools. Some might say that about all of us that have M3s, and not 5.0 GTs, or Camaros, or another car.
Give it a rest. You like the Megan exhaust, and it's less than half the price of the more common ones mentioned here. We get it. Glad you like it, perhaps I'll like it enough to buy one too, perhaps I won't. But I'm not going to assume that those that bought and Akra, Eisenmann, or similar are fools either.
