2012 bmw 335is quad exhaust conversion

Hi,

I am new to the forum. I have a 335is and is wanting to go with a quad exhaust tips on the current oem setup.

My question is that would a quad diffuser that fits the m-tech bumper fit on my oem bumper?

Second question is that what are the tips available? Hoping to have somewhere around 90mm od for each of the tips.



Thanks in advance.
