The increased noise from the turbo muffler has not resulted in mpg gains obviously....I would say not really noticeable power difference either....I am going to return to oem equivalent muffler soon....Only really noticeable improvement was in coasting distance. I think ideally the transmission and engine computers(or valvebody/torque converter at least) would need to be reprogrammed to really harness advantage of more open exhaust. AW-4 is wasteful...
