header question

i currently own a 1972 buick skylark i want to convert it to dual exhaust
my question is what is the best headers and exhaust to get for sound plus horsepower any imput would be helpful thanks

Ed, I would go with a set of headers from TA Performance (taperformance.com). These are mandrel bent headers that will bolt right into place on your '72. You can also have them jet hotted (ceramic coated) as well.
I have a '69 Skylark, and the only place I do my shopping is TA.
