Thanks, F87!! I was all excited about the MPE & then I found the rest of the mods this past weekend. I figured I had some kind of DP - this car is loud. Doesn't stink though so knew I had a CAT at least.
I have seen where the DP is - I reached down to try & see if I could feel a stamp or logo. That was how I figured out it was the Wagner. I didn't know to check for the things you mentioned below so I'll do that this weekend & report back. My buddy was under the car & he said there were no cuts or mods to the pipe & he could see the sport DP/cat underneath, too.
He thinks I'm weird... he loves the drone. LOL LOL LOL
I did look under the engine cover & under the power tap under the hood (where I installed my active autowerke 8 on my M235) and there was nothing attached, didn't see any other wires, no box anywhere.
Thanks a lot for the advice & what I need to look for.
Any chance you know this -- if the ECU was flashed, can that be put back to stock??

If not you most likely have a tune or else you would have gotten a check engine light from the high flow cat, unless this particular car is not sensitive to high flow downpipes.
Overall those are some good mods, congrats on the car.
