Diffuser options

[gemini.m3]

I know this has been covered on the board, but most of the threads I have found are older and some of the suggest diffusers are not made anymore (iCarbon)

What are some options outside of the BMW Performance one? If you want like a 2 fin or 1 fin single exhaust tip? Modbardgins? RW Carbon?

Running out of aesthetic mods and this is my next one to do alongside the BMWP mirror caps!

You know given that the bottom of our cars are flat and that the rear end tends to be on the light side at speed....makes you wonder why BMW never actually built a real rear diffuser back there?

Cost/Benefit: Higher cost to build and not much benefit at legal speeds.

I prefer to call what is available for the 135i a rear valance.
val·ance/ˈvaləns/
noun
a length of decorative drapery attached to the canopy or frame of a bed in order to screen the structure or the space beneath it.

EAS makes one for the M3 for $1,700, looks like it would work but have not seen any testing results.
