I don't buy into the unequal manifold theory. I have heard plenty of subaru's with aftermarket manifolds that don't sound like any inline 4 I have ever heard (granted not many equal length manifolds are being made...).
I just went to a pro rally in PA, and you could always tell when it was a subaru coming around the corner, and many of these cars are *highly* modified open class and group n rally cars.
It might make the difference in sound even greater, but I don't believe its the ultimate cause. Probably has more to do with firing order/timing, much like the dirty sound of a harley. Just a guess...
