TTI. Shorties

I would like to hear what experiences someone has had with the TTI SHORTY headers in a 440 dart. Would there be less interference with everything due to one 3" pipe vs 4 1.3/4" pipes going by the starter, t bars,.......

I know there will be a small sacrifice in performance over long tubes , but much better than manifolds. Maybe a good compromise ?
thanks. :usflag:
