ok so i ordered a set of ceramic coated headers from BBK performance for my 06 GT they came and looked great . . the next day i took them to steeda to have them installed and i get a call an hour later from steeda saying " are you aware that these headers use circular ports and your engine exhaust is "D" shaped" . . what is with that why wouldnt BBK make D port shaped headers to fit the engine better? Am i missing something here??[sm=feedback.gif]
