yea it probably isnt really a do it your self but i did find a kit online with all the proper sanding heads and it said to use an electric drill or a dremel tool of which i have both. 200-400 sounds a little bit too much for me especially since i wont see a huge gain in power. also do you think it is really worth it i am only paying 60 for the header so i dont see sense in paying a large amount of money when i could get a brand new header for the same price.
