Z4M Modified back boxes

Post by captainmorgan999 » Thu May 25, 2017 3:30 pm

Hi, following a recent upgrade, I now have my modified back boxes for sale. They were modified by MVT in Poole and they did a great job and they sound great :thumbsup: I will add photos later :)

£350 plus £20 postage.

Probably would have helped if I had stated that :?

The boxes were cut open the perforated internal pipe was replaced with non perforated and then the stuffing put back in. It is a a good upgrade if you are after a little more noise and a few pops :evil:

Sounds interesting, I may be tempted. Any chance of a video before you remove them? Wouldn't want to fit them in case they're too loud as that happened to a mate of mine with modded back boxes on his z4m.

I have uploaded a photo of the boxes which shows where the panels were cut/replaced. I stupidly didnt take any video of them before taking them off. With regards to sound, they are slightly more throaty than the originals, they don't have any drone. IMO they are a great upgrade if you want a little more bite to the sound without it being overwhelming or too loud.
