Contrary to other comments, after 2 weeks of use, it has gotten about 20-25% quieter. The only time it seems overly loud to me is on cold start, and I will probably go to the AA tune to get rid of that.
The same thing happened to me concerning a left shift of the exhaust. Make sure you really tighten the bolts on the connecting crossbar. The cost of shortening my pipes and repositioning the brackets was $150 at my exhaust shop. Well worth the cost.
I appreciate your feedback. My AA exhaust on my E36 M3 mellowed out after a couple weeks and it's good to hear it may happen here too.
It is definitely SEX when you get on it, but it seems louder (drone wise) down low than when I rev it.
