John Cooper works mini Exhaust (Twin centre pipes) Help !

[prmoldoaks]

Hi guy's, my son wants to buy a mini cooper and spec it up like the challenge car, he wants to add the central pair of exhausts.

He's looking at a Mini Cooper R56.

Does anyone know if this exhaust will fit, someone told him that the battery box is in the way for these pipes, we know we will have to fit a new rear bumper/diffusers for central outlet.

Thanks guys in advance
