it does cost mint to build these things. i have at least $2000 in parts and coating and at least another $2000 in labor and procrastination. you pay for the skill of the fabricator and the parts to build them. look closely at all the parts that go into putting them together not to mention getting them to fit the a-body chassis. my headers aren't small and i was able to get 3 out of the 4 pipes on each side inside the chassis. custom built flanges to match the exhaust ports. the pipes start out at 2 3/8" for 6" then go to 2 1/2" for 6" then the 2 5/8" for 22" into a custom 5" collector. it takes a heap of procrastination to build them which cost per hour. look down on the floor and you'll see the rest of the exhaust system. perfweldheaders hit the price right on the nose.
