As you can see, the exhaust manifold, stock, was made to resemble a
header type construction. Also, notice the dual pipes
that split off the manifold. This makes it possible to add a
turbocharger to the intake. The part that usually fails first is
at point 11.
IF you wanted to make TRUE duals, with true dual cats (EPA), and dual mufflers, you'd have to cut the existing cat off (unbolt it), and add two smaller ones. There is also; a Dual in, Dual out catalytic coverter for dual conversion. In states where emissions testing is not required, but catalysts are, the dual cats & mufflers are for you.
If you do not want to remove the cat, you can have a muffler shop custom bendyou the pipe, and make you a custom dual exhaust, AFTER the catalyst. You can have two mufflers also - or -you can also put a muffler with one inlet, and two outlets, and have them bend the pipe for you.
Custome pipes will have to come out opposite sides of the gas tank. They can be run straight out, or bent down towards the ground a bit. They must run up over the rear axel, but, can run under the axel carefully, and the clearance for up-lift should be considered (my original duals were run this way, since I only ride street). The pipes out the back will clamp to the holes that exist in the rear bar that goes across the gas tank. Use rubber mounts, solid mounts will just break (mine did many times, till I switched to rubber mounts). If you are going to use two seperate mufflers, make sure the muffler clears the brake and gas lines back there on the passenger side! On my first set of duals this way, one muffler was rubbing on these lines. The Muffler had to be turned almost straight up and down. A small adjustment in the pipe path will fix that problem.
So, as you can see duals are very possible, and will work just fine.
