Pipes be like music, tastes vary.
Mine likes the sound of four into ones, and that CBX. F1 like to my ear.
But all my 4 cylinder machines have had the 4 into 4 pipes, because I like to look at them, symmetry is a fundamental aspect of beauty.
Just because my thoughts are on the sound of machines, I love the sound of a Mustang Cobra V8; but the new Corvette would be my choice.
