I have been looking into doing the switch to a quad exhaust setup and I really do not like the look of exposed CF or the fin options available for e9x diffusers.

Does anyone know where to find this diffuser or something like it for the mTech/mSport rear bumper? Or does anyone have experience trimming their own diffuser?

This looks like an OEM Msport diffuser that has modified exhaust cutouts in order to fit the quad tips.

You can either do that (and risk hacking up your stock diffuser), or you can buy a carbon fiber quad diffuser from a vendor - I recommend RW Carbon, as I have purchased from them before, and they do have quad diffusers.

That is just a modified OEM m-sport diffuser. There are tons of DIY on this forum.
It's pretty simple to do, but may take time to master if you've never used a dremel. In simplified terms, basically just copy the shape of the cutout and draw an outline where the other exhaust is going to be. Use dremel tool and cut with a steady hand. Use high grit sand paper to remove rough edges. done.

Or you can purchase some after market quad diffusers for about $250.

Looks like I just found the thread where that picture originated, he did end up doing a DIY cutout on the diffuser.

I might just end up doing that. Thanks guys.
