Hit them up to see if they can sell the diffuser only...

 

i have the mtech bumper 2007 .. thats not the one

 

You def need to post a picture of what you have.

 

+1.

Judging off the link provided by DC4rob you don't have an mtech bumper as THAT is in fact what an mtech original and replica looks like. Only 3 options can be guessed as to what you have and since the factory and mtech (rep or legit) has been crossed off that list you must have an OEM M5 bumper or a replica M5tech. I could be wrong, but seems to be that way.

 

Pic on Top is OEM m5. The one on bottom is OEM mtech. which one is yours.?

 

U r missing the middle rear underneath cover right?
