Just wanted to know how you did the R&D for your headers. They seem to make power pretty good and are very inexpensive compared to other brands especially for the K series. Just curious on how you came up with the design for them and if you yourself make them. A couple buddies of mine are interested that have FG's but they are leaning toward the SSR race header instead. If you can give me some more info that would be great. Thanks vteckidd!!!!!!!!
