I just did this conversion from a regular Msport Diffuser to M5 Diffuser. Thank you for the DIY guides. It took me 2 hours at least but it is well worth it. I replaced the adapter and the CA (Comfort Access) is working like a charm.
I have an appointment next week to install my M5 Quad muffler so i am excited and hoping that the muffler install doesn't get too complicated.
Also today my Cyba 90MM Dark Black Quad Tips arrived and they look nice!
Here is a picture of the M5 Diffuser without the Quad yet
If anyone located on the Island need my help with this conversion, just hit me up and i don't mind helping out as long as you bring some beer for refresher
