You didn't get what I was saying apparently. Just because the Borla worked(without drone) for you and your friends on other vehicles, doesn't mean it's going to not drone on this car. For the record, I am quite happy with my system. I believe it's because I kept the OEM resonator(as many here on the forum have advised). And after the N.W.'s downpipes, used a Magnaflow tru-x crossover pipe in place of the factory H-balance tube. My Magnaflow SRT6 resonator back muffler sounds great IMO. No dynos for me at this time, but it sure feels like 20whp(or maybe it just sounds like 20whp). If it was a track only car, then I might drop the heavy resonator and wear ear plugs. When you get your system completed and it doesn't drone somewhere between 1800-2500 RPM; then I will be happy for you. Then again, perhaps you don't care about a little drone. I'm certain that the AMG boys had to work hard on that resonator to cancel the bad frequency(apparently between 133-138Hz for those that may be interested. lol) I admire all the guys and vendors here on the Forum who have pushed the limits(and spent a lot of money), and figured this stuff out. Compared to them, I'm just a follower here(and like them, I too have spent a lot of money).
