I wanted a Corvette my whole life, but I never dreamed of all the wonderful people I would meet because of it!
Through my experiences I have found that, while headers do look cool when you have the hood up at a show, they are not worth the expense if you are building a street cruiser unless you have a "ground pounder" of a motor or plan on doing some racing. They make the car noisey inside and for the street their benefits are negligable. After having headers on some earlier street use performance cars I went back to the tried and true 2" ram horns on my '77. You can have them ceramic coated in a variety of colors, install stn. stl. exhausts and I feel they look just as good as the headers do. As far as performance, while the headers will give you better flow you will never notice the difference on the street. I am sure that some of the other guys will have another opinion but for my money, that is the way I would go.
