Diffuser and 3.5" inch quad exhaust mods

What's up fellas, received today a carbon fiber diffuser and 3.5" inch quad exhaust tips. Will probably be working on the installation this weekend.

Sweet!

I've been scouting for a good looking carbon fiber lower bumper/diffuser combo and this seems to be what I'm looking for. Could you share more info. of where you got them from - maybe some links? Thanks!

Did you change your mufflers? The exhaust tips look like they have one inlet. The sport exhaust on the M sport has 2 pipes coming off each side. Are those adaptable?
And if you can take some pics of the install for the diffuser that would be great. Thanks!

Not yet... will be working on it soon. I got my hands on M6 comp mufflers so will be installing those instead.

The tips have 1 inlet and 2 outlets which works on the 640i. The black tips I returned because I wanted gloss black and it came matt. I exchanged them for titanium ones and those look nice. I'm either going to sell these or return them.

As soon as I complete the mod will post pics. These are the titanium tips. 2.5" inlet and 3.5" outlet.

The exhaust is M competition and the tips i sourced directly from China perfect fit.

Thinking of putting together a group buy if enough interest. I ordered the tips last Sunday and Friday afternoon they were delivered.

Thanks! The diffuser fits perfectly, EXCEPT it wont stay on the car you will need to take it to a body shop and they will urethane it on which means its NEVER coming off. Another member on here had the same issue, he paid $75 for the install I paid $150.

Here is the ebay link:

It's only been a few weeks so the tips are perfect.

Now the drone does get annoying and sometimes I wish I wouldn't have changed out the mufflers but it's to late to undo. I have the mufflers flaps/valves open all the time I'm going to close one side and see if there is less drone.

At cold start the car sounds awesome.
