318 exhaust

are you planning on running headers or keeping stock manifolds?honestly i think a 2.5 x pipe off stock manifolds would be kinda a waste.if you plan on keeping your stock manifolds id stick with a small dual system like 2" or 2.25" no larger.also dont under estimate how well a good single exhaust can work.look at the way the commando 273 exhaust systems were built.not only did they flow well they have a unique and cool sound to them,and they were a single....just food for thought.
