Revel Medallion Touring-S exhaust system for 16-17 Lexus GS F (T70201AR)

Is this the full catback exhaust or just the axle back?And any noticeable performance gains compared to stock exhaust?

From my understanding F cars equipped with axle back systems or cold air intakes don't give much difference in gains. On the other hand, Headers and midpipe will feel more powerful. This car sounds as it only has axle back.
