Axle back for all show no go? You said in your last post that an exhaust isn't a "go fast" mod and others have stated this full system shouldn't show much power gains. So how is it better than an axle back? I think that if this exhaust DOES "create more flow, less back pressure, and increase efficiency of other mods" then we should see power gains. Especially on a car that already has intakes, dp's, and increased boost. What am I missing here?
