I would like to know why Ford is using a exhaust pipe diameter that is smaller that the 2014's. The cfm flow rate of the throttle body and intake tube would be nice to know too.
I read that Ford added the mid-pipe chamber mufflers and smaller piping to meet global noise standards due to the fact that the mustang is now going on sale outside of the US. I'd be a lot more expensive to have "US pipes" and "euro pipes" so they just reduced the size for all of them, I'd assume.
2015 mustang GT, Performance Pack, Recaro seats, All-weather floor mats.
