I’ve changed from 2.5 then 2.75 and now a true 3” item also changed numerous amounts of exhausts on other Subaru’s never needed a map
a few people I know have gone for a so called fruitless tweak we’re its made no difference on the drive back to when they took it....from the mappers unless you are taking the downpipe cat off and deccatting the centre piece and back box have no effect on the map through experience
