AA Exhaust...

kmac1980 · 09-10-2009, 12:36 PM

Finally got my AA Exhaust on my E93. I must say this is a beautiful looking piece and the sound/tone is very nice.

However, I find it has a very deep drone from 1000-2200rpms, where you spend a lot of time rolling around in 2nd gear in city driving. It's actually amazing how it gets quiet around 3000rpms, like other members have posted.

With the top down its almost annoyingly boomy cruising around the city, however, top up, windows up its quite reasonable.

Any other E93rs notice this? Do you just get used to it over time?

Give it about 300 miles and it will quiet down (I know my AA exhaust did)

funny... mine definitely got louder over time. Just like every other exhaust I have ever owned.

But you do get used to it so after awhile it's not as noticeable as when you first get it so it quite often seems quieter.

Thanks for the tip, I hope so! Does it ACTUALLY quiet down or do you get used to it? Were you running stock middle exhaust with it or aftermarket?

No, it actually lost a lot of the deep drone that it had. I'm pretty sensitive to drone, so it definitely improved.

Awsome, thanks for the info man, but were you running a stock middle exhaust at the time?

Damn...good point. I was actually running the Fabspeed non-resonated x-pipe at the time

Just sell it to me Kev (at a big discount of course)

By the way - the car you saw - heard (black e92) only had the rear section.

It sounds incredible, i think i'll live with the drone and see if I get used to it....if not, I'll be in touch LOL! It definitely wouldnt be as bad in an E90 like yours or E92

You will get used to it - I guess with the top down its more noticeable - how about with top up?

I think i will have to pull the trigger on one of these soon.

Yeah, thats why I was saying the e92/e90 it would be very liveable, when I have my top and windows up its very mild.

I think this loud booming sound in the 1000-2000 RPM range is common in most of the aftermarket exhaust. My Vanguard Ti Exhaust has this as well, but it does quiet down over 2K RPM. Even the stock exhaust was droning in this range under load in the lower gears.

Yeah I hear that, but I'm talking under almost no load, even sometimes when you let off the gas and you decelerate in 2nd through the 2000-1000 range its still very boomy!

Whats weird, is I found a spot around 1800rpms that with very gentle throttle it goes very quiet...but damned hard to keep it there!

M3ltdown · 09-10-2009, 02:07 PM

well... you could do what I do and just keep the revs over 2K RPM at all times... the only downside would be less gas mileage

SlammedR8 · 09-10-2009, 02:14 PM

I think it will get a bit louder over time, and if not louder. it will sound better . My eisenmann sounded better after 1500-2500 km

cool, do you notice drone more top down vs. top up/windows up with your setup?

Umm...its hard to say! but I would say that its a bit louder with top closed because it echos within the cabin kind of. but its a lot clearer & cleaner sounding with top down because you hear all the little noises of the exhaust. (which is my fav part of the exhaust TBH).

By the way, I forgot to mention above, it will sound more clear (or at least my Eisenmann did) it sounded almost muffled when it was new, but once it opened up it got a much more clear & clean sound if you know what I mean.

Omar@ActiveAutowerke · 09-10-2009, 02:55 PM

Congrats on the new system and thank you for choosing the Active Autowerke Signature Exhaust for your M.

The reason you will notice an increase around 1k-2k is because that is when the engine is "dragging".. The term "drone" is usually associated with the "booming" sound while cruising around 3k-3500k. We went through a few different designs before deciding on our current design with the Noise Cancellation Chambers to address this issue.

I have HFC's and X-pipe from Fabspeed. No louder as in what slammedm3 said.

It will be slightly louder once broken in. I wouldn't say it's more "boomy", just a bit louder, definitely a bit more aggressive as it does sound a bit muffled when first installed.
