By firing or pulsing in a circular manner the signal is the same for all cylinders, the merge collector is suited to the even 180deg pulse, while the larger volume collector typical of most conventional non crossover exhausts helps accomodate the uneven pulse's. You will also find that with the 180deg system you can use a smaller dia tailpipe than you will require with the conventional type. (270/180/90/180) pulse interval's.
