Of those mfg that you spoke with, how well will there headers mate up to the Rousch X-pipe?the couple mfg i have talked to that have test fit they fit fine so far, i don't see there being any changes on them
yes, everyone will be confirming once they have a car in house i would venture to guessAmerican racing headers confirm to me that my 2015 ARH long tube headers will fit the 2018.
all the headers will fit, no changes for 18will SW headers fit?
