Greetings.

Is it possible to upgrade a Z4 3.0i with quad exhausts, by putting the left and right genuine BMW Z4M silencers?
If by buying the whole trunk floor trim panel for the Z4M and by removing the battery how will the part ,where the battery currently is,be covered ?

I currently have quad exhausts with one silencer.

It is but would be quite long winded.

Might be more worth your while just having a t piece from the left hand side exhaust and bring it between the boot floor and your bumper.

That's what I currently have..(really dont like the feel and look)
That's why I am going to upgrade to the Z4M exhausts style.

In this thread the current battery box is resized and fitted again in the same place.
The thing is how will the hole at the place of my battery box be covered.
My battery will be placed at the top right part of the trunk.

Yes, it is possible (I did it on my 2.5i). However, you will have to move both the battery box and the EVAP canister. The M puts the canister dead center and the battery is in the trunk. Once you clear the "path" though, it's very nearly a straight bolt on affair.

As mentioned previously Z4M exhaust system will be installed.
All parts needed were ordered new and have arrived.Project starts this week.

My previous quad exhausts style.


Pictures of the project coming soon.

That's exactly how they fit.

just buy some adjustable hangers, you can really fine tune the muffler tips to perfection..... i use the dkf adjustable hangers.... they are only like 120 quid but really really allow you to get perfect fitment, they are idea for secondary setups like what you've done to just get the last bit right, lots of the these quad conversions see to sit a little funny imo... the hangers allow, side to side and lots of up and down adjustment, more than enough to get your tips tight up to that bumper..

They look nice, should be able to knock a pair of them up no problem.
