I finally got my MBRP exhaust installed. There were a lot of people worried if it would work on a L99/A6. I can tell you everything fits just fine. As far as the drone/buzz at low RPM when the AFM kicks in, it is there but not bad. You can definitely here the engine kick in and out of 4 and 8 cylinder mode. That is going to be something I'm going to talk with MBRP for a solution as this might annoy some out there. But by far, IMHO, does not take away from what this exhaust can do for your L99/A6. The sound is just awesome and it is the way GM should done it. I have a few pictures to give everyone an idea of what comes in this system and after pictures. Enjoy! One thing I want to point out in the videos, the videos do not do this exhaust justice. Its more impressive in person
Great Job MBRP!
Install Notes:
It was not that this was hard to put on, just time consuming, really. An extra body would have been nice but that person might have just been in the way. I am going to have to go back under and do some "massaging" left bank back and twist the position of the XPipe to get everything lined up better. It's only a fraction of movement and nothing to worry about. I had issues with the Left Tip install. It's very hard to get to bolt to tighten it down. I suggest having a small 1/4 inch drive with a long extension. The rear diffuser is very fragile so be careful when removing the stock exhaust. Also all clamps for the piping on the stock and MBRP system are 15 mm DEEP Socket and the bolts for the tips are 17 mm.
Little George has been waiting for this day to, lol. MBRP should really think about putting the Camaro on the package and replace that horrible looking Mustang
Neatly packaged
Nice Cans!

You can almost see all the way through the can if it weren't for the bend on the tip (exit)

Beautiful Tips!
An upgrade in Size, Very nice!!!
One last look at the stock tip, you can see inside that the diameter is much smaller than the newer MBRP tips, very nice!!!
Here is a look at the fit check before getting ready to install.
Ok, got it in and its looking much better.

And here is a 2 minute video of some various stuff that I know I wanted to see when I was hunting that new sound. Enjoy!
LOL After I removed the stock exhaust, I decided to have some fun
