Holy Crap... that is a "tad" bit loud 
haha. You should get some driveby clips during the daytime as well
I definitely sounds amazing though. Our headers do have a very unique sound to them because of their design, and you get to hear it more with your specific setup since its basically open headers
. You could always just replace the rear muffler with a 14" 5x8 magnaflow (link below, you can bargain with them too) to smoothen the sound a bit while reducing the drone significantly down the road if you want to, but either way, sounds great!

Move the video camera away from directly behind the exhaust pipe. Perhaps try off to the side a bit and further back.
The mic on the camera makes it distort the sound.

I agree, putting the camera at a 45 degree angle or from the side of the exhaust tips will prevent mic from picking up distortion & wind noise from exhaust gasses. Also a video of a driveby of the car under full throttle load would be nice too to get a better idea of what it sounds like.

pulled the cel codes......
well I pulled the codes today........seems my o2's are good as well as my MAF.......the codes were for fuel trim on the right and left bank......PO170 and PO173.....my friend told me (BMW, Porsche tech)my setup may have put my ECU outside it stock parameters but he is not sure on a MB.....He said I may need a tune to compensate.....or is it something else?

Have you changed your fuel filter recently? I think that's the big part that can get clogged and make you lean out (based on the code, I'm assuming that's the problem).

If your O2 sensors have not been replaced it will cause your air fuels to be out of spec. Again, O2 sensor codes will only go off if they completely die or are close too it but it takes a long time for that to happen. They still be well out of spec thereby causing your fuel ratios to be off.
If your upstream O2 sensors (before primaries) have never been replaced and you have no maintenance records of having been replaced... then its time to do some maintenance. The same is true of MAFs as well, over time they too go out of spec and replacing that can make a big difference also.
ECU upgrade can help but it won't guarantee to fix the problem because if your stock sensors are out of spec, no amount of tune will cure the problem; it will only be a temporary band aid.
