13" RS7 vs S7 rear bumper

[Andreasmkr]

Anyone know if they use the same rear bumper on these cars except for the valance(diffuser)?

RS7 part number: 4G8807441B
S7 part number: 4G8807441A

Can I then retrofit a original Audi rs7 rear diffuser to my S7 rear body? [wrench][confused]

No, If you want to fit the RS7 valance, you need RS7 the bumper also.

Okay. Much appreciated for the answer
