dart headers

TTI are kind of a rip off for the money,I have no idea about dougs,if your going to spend the $700 for a set of ttis do yourself a favor and have some custom made,otherwise I would just live with a cheap set.Ive got a few buddys running ttis and they have all had some issues from minor to major,but whats really bad is the fact they will lie through their teeth about the issues and their step header is misleading since it wont make any more h.p. more than a cheap set of 1 5/8s.
