Photos from IAA:

Per Drillslinger: the system shown is cat-back ("Evolution" system) with resonators and the valve option. When the valve is closed exhaust gases go through the muffler and out the inner tips. When open, the muffler route remains open but the path of least resistance becomes straight out the drivers outer tip and across (over the muffler) to the passenger side outer tip.

Hey Thanks David for the pics

ZCP M3 · 09-22-2011, 01:38 PM

I must say it is a very slick design with the valve diverting exhaust through the outer or inner tips.

If only those damn tips didn't cost so much!

You probably get screwed by the currency conversion. At $2091 USD, the slip-on isn't too outrageous, considering I paid $1800 USD for my E46 M3's Dixis titanium muffler 5 years ago. The additional $2400 USD for the titanium midpipe is fairly insane though. Then you get to the tips at $1400 USD which makes them automotive equivalent of a woman's thong: minimum material at maximum price.

The slip-on with wireless control intrigues me. If there's a noticeable difference in noise between the two modes I may end up purchasing one.

Dackel for President!, thx mate!

Que-est-ce-que-F%CK?:
"Hard Facts

*Preliminary data"

, In Germany I would expect them to be be tarred and feathered for less

Amazing product though! Wish it would make more sense to afford it.

Wonder when Akrapovic are going to produce a video of this system?

VIDEO!

RaptorKTM · 09-26-2011, 10:54 AM

I went for the full system, I hope I dont regret it.

1560 · 09-26-2011, 11:07 AM

excuse for being sceptic

"hard facts"
and then: "preliminary data"

I want one, if it does what it says,
and if it sounds like the GPsafety car
and if it sounds good when you're in the car

I'm not going to spent so much, only to amuse bystanders

x1kc · 09-26-2011, 11:07 AM

quick question, my 1M is currently in production
looking to purchase an exhaust for it since I do not think I would enjoy the drone...

Heard that the Eisenmann exhaust still has a slight drone to it
No comments from the Supersprint
How bout from Akrapovic? Guess no one is actually running it yet, but how about information from the dealers

my Akra dealer has 3 on order,
also, each exhaust needs a few 1000miles/km's to "burn in"
so the "full sound" isn't there in the beginning!!!

Akra isn't delivering yet (in .BE)

momo style · 09-26-2011, 11:13 AM

how much did you pay for the whole system??

momo style · 09-26-2011, 11:14 AM

do you think the slip on will make the same noise as the full system?

Possible to get direct information about if drone is present or not
and report back after your testing as well

also, if the slip on will sound similar if not same as the ones in the videos

I have a friend who put the Eisenmann (TUV version) exhaust on his e93 335i. She was really dissapointed by the sound. Not much louder than stock. I have heard that IF you want sound.. get Eisenmann's "race system" bc their street TUV exhausts are too quiet. I think for a 335i BMW's Performance Exhaust sounds nice enough for the price.

I have yet to hear a Akrapovic "live". Maybe when I go to the Essen Motor Show in Dec.

doesnt quite answer my question regarding the drone
I do not doubt the sound level of the exhaust, but I've read that the eisenmann exhaust for the 1M does produce a small amount of drone
and was wondering if its the same for akrapovic and supersprint that was my question

M ETT · 09-26-2011, 11:33 AM

Dackel is the greatest. Best pics of the Akra I've seen so far.
Damn, that Cat-back system is expensive, but right now I want it so bad...

I do not know the answer to your question. That is why I did not comment on it.

perhaps try contacting a dealer like Harold or Akrapovic directly to see what thier thoughts are. ?
