Reading the article of exhausts (i.e. from the back pressure thread) the other day brought this to mind:
Seems that a number of exhaust manifolds have a 4-2-1 configuration, if you had just 4-2 with the two pipes running to two separate cats and then on through two separate systems out of the back of the car, all other things being equal (bore, box size, cat size etc...) with the original factory standard would it give any increase in power?
