Fitting a 4 pipe exhaust and a diffuser on a 114i

Hi guys.

Does anybody have experience with putting a 4 pipe exhaust on a 114i/116i/118i with an msport kit?

I have a 2013 114i with the msport kit and currently only one tiny exhaust pipe. I would like two dual pipes and a diffuser.

The problem is as follows:

An ordinary f20 has the pipe in the center of the panel on the left side of the number plate. Here is a two pipe specimen.

A m135i has pipes further towards the middle.

Any diffuser I can find made for 4 pipes have the hole somewhere between the hole on a 114i and a m135i.

It looks like 4 pipe exhausts are made to extend the holes both ways. Just like this m135i.

Here is a picture of the diffuser on a 114i.

As you can see a dual exhaust on each side will not fit the holes. Unless some manufacturer makes a version where the two pipes on each side are not centered around the original pipe. I havn't been able to find one.

Has anybody here done this before? Will I really need to chose if I want the 4 pipes or the diffuser?

Go to a local exhaust shop and get a custom one so position of tips won't be a problem.
