i ask because i really like the miltek non res so i know how loud a car can get after a downpipe. so yea youre right i would have to get the res version if i planned on getting a dp down the road.A downpipe upgrade is not required for tuning but it makes more of a performance difference than any other bolt on part short of a turbocharger upgrade so we do typically recommend them strongly. You can absolutely tune without one though.
