no its still a total of 6 inch becauses exhaust travels through both pipes. in turbo world bigger is always better as well. hands down dual systems wethere its ems, berks, deperature 2 etc. will out flow single setups liek apexi n1 and blitz. most people buy the single system becauses they like the look,sound etc. the only major advanatages are singles usually are a tad lighter.
