I was bugged to death about converting my old s2000 into a single 3-4" exhaust and that id see large gains. on a stock non turbo car however I would completely agree with you which is why I said it was retarded of the g35 owner to convert his stoc exhaust into a single 3" The only possible fault w/ dual exhaust on a turbo car is POSSIBLY turbulence. Other than that, there’s really no issue. My Subaru runs a dual exhaust, as does my 911. There’s no issue to it at all. --- _[View the full topic](https://forums.speedlife.net/t/sightings-thread/234818)._
