hedman "tight tube" hedders?

Great job they did , let us know how they perform , better than what they replaced ? It's great to see all the tight tube headers , you got clearance , good performance , maybe 5-10 hp less than TTI and the same or better than regular headers and manifolds . Been 2 years now and stiil happy with my Hedman tight tubes . Now to solve the traction and gearing , no more 13.8 . I want 12. something this year !
