I was wondering on the different ways the slant6 has had different duel exhaust setups made. Especially using the original exhaust manifold. On the Dutra Duel I understand that its made to use the rear part of the original manifold for the choke pocket and the front is a special cast.
I have also been seeing where they take the same idea of the Dutra Duel but, keep the front half from the original manifold and adding an exhaust outlet to it. This basically gives you a Dutra Duel exhaust.
What exactly would be the difference between the two? Why couldn't someone just keep the original exhaust in one piece and add the exhaust outlet to the first three runners? Wouldn't this also balance the duel exhaust from the get go? Just curious
