all you had to do was go two pages back...two corks, doesn't kill the drone completely but it does help.

The exhaust sounds so good without the VRRROOOMM drone around 2k rpm.
so what did you end up doing? different bushings or corks?

If the drone is noticeable and people are complaining, why doesn't AA redesign their exhaust? I like my mods to work right out of the box- no tinfoil, no duct tape, peanuts, or corks required.

edit: Whoops.. sorry monkey, quoted the wrong post.

it's only noticeably loud when you hit 2-2.5k rpm. I do a lot of high way driving so I just switch to 5th gear on the highway and it disappears. But it is a beautiful sounding exhaust.

I had AA on my M3.. let's say I was fairly disappointed. Drone is a deal killer for me.

To be honest guys, any aftermarket exhaust will have drone. It is impossible to avoid, and drone is "subjective". I do agree that my AA is louder than the other exhaust systems, i.e. Eisenmann, Remus, etc. However, the Eisenmann and Remus both do have drone IMO. But you are paying a premium for it.

However, compared to a muffler delete and the Ikon, the AA exhaust is not that bad at all. It's just at 2-2.5k. Above that range or below it sounds completely stock. If AA can find a fix, as I said before, I will be an extremely happy customer since I do love the sound.

I will do a resonator delete if AA can somehow find a solution to minimize the drone.

Will the fix be applicable to current AA N52 exhausts?

We will have to see.. I have a customer coming next week for a dyno and to try a couple things. From what I can tell it happens when the car is in D and lugging the engine in a high gear for the speed its traveling.

It also happens if the car is in manual mode too.

Do you have first hand experience with droning from an Ikon? Other Ikon owners claim no drone, even with resonator deletes.

Shit - you were in mine... D and DS, ANY speed, acceleration between 2k-2.5k rpm, more load (uphill) more drone.

A fix would be in order, in my opinion. I'm ready to get rid of mine.

I think he meant put it in sport mode and change the gear so you're not in the range of the drone.

Yeah put the rubber dampener from the stock exhaust onto him exhaust. It helped with the vibrations but mind you this customer never complained about anything to begin with.
