I know that the new mustang's exhuast system from the factory is pretty good. Is there any performance to go with the catback or just to buy an axleback system? I know that replacing the mid section and long tube headers is a no-brainer. Which axle-back or cat-backs have actually made more power or is just souly for sound on this car?
