Exhaust Comparison: Akrapovic vs. Dinan vs. Eisenmann
 

Starting this thread as discussion from another thread.

Have you heard sound comparison of Dinan vs. Eisenmann vs Akrapovic?

I have heard Eisenmann and Akrapovic, and like the Akrapovic.

Nice ride..congrats

here is the thread about the dinan free flow exhaust from another forum. Was researching Dinan last week and came accross this thread:

Dinan High Perf Free Flow exhaust install - XBimmers.com | BMW X6 Forum X5 Forum

Will probably do it once spring hits here in the northeast....;).

LeMans why are the three priced so differently? The Akrapovic system is quite a few grand more than the Dinan...thanks.

Akrapovic is titanium.

Loaded question, so here is the answer.
In brief, What you pay is what you get(no offense).

I have Eisenmann Race exhaust on one of my BMWs and I have closely examined and heard Dinan and Akrapovic on few occasions. Akrapovic just stands out in comparison to others.

If you look at construction of three, Akrapovic is the most detailed and intricate, with better material(Titanium), workmanship and quality. Dinan is the cheapest looking of three. ;)
Akrapovic is the lightest of three. Dinan for some reason does not state the weight of their exhaust, but is unofficially known to be heaviest.
Akrapovic is biggest setup(see pics below) and they also proivides the detailed information about their exhaust.

See pics and videos of 3 below.

You can get better than list prices on Eisenmann and Akrapovic.
Best comparison is seeing and hearing the three in person. I am getting Akrapovic next time. ;)
BMW also uses Akrapovic on their Safety cars...see videos below.

Comparison chart:

----------------HP Gain----------Torque (Nm)---------------------------Weight (lbs)

Eisenmann-----14(Unofficial)--------?----------------------------------------53.2
Dinan--------------8 -----------------7 lb-ft @6000 rpm ------------------------?
Stock -----------------------------------------------------------------------------103

If these are set up the same way as they are for the ///M3, Akra is priced for a full system where as the others are slip on's. For the ///M3 once you add the mid-pipe you are fairly close in price........Phil

Thanks LeMans for starting this thread..The pics explain them all..:D

Sorry for the noob questions: catless downpipes refer to system without catalytic converters? I did read somewhere that there is a slight improvement in performance with the catless downpipes. Is it legal not to have catalytic converters?

Thanks in advance.

Not legal and in most states it won't pass inspection........Phil

Where can you get better than list pricing on the full Akra?

+1...on list price of Akra....

+2 on the Akrapovic. I've been looking around but no one wants to budge on price.

Quality wise Akrapovic definately looks like a high quality craftsmanship, and the fact the BMW uses it too, that's a plus.

Like was mentioned before, you get what you pay for.

Sounds good..noob q though: why does it sound that it is sputtering towards the middle of the video?

sounds awesome!

how does it sound during regular, city driving? barely louder than stock?

I feel as if none of these online videos do any justice for these exhaust systems... I mean the videos don't sound bad at all, however, in person its so much more amazing! Full Akra is awesome and top notch esp with that price :/
Def need an exhaust just don't know which one to pull the trigger on.

Might as well go with Akrapovic. I looked at their instruction pdf file, step by step with pictures. Definately looks like a high quality product with great support and instructions. :thumbup:

If you add the downpipes....track rated in US

Eisenmann Race on F10 M5

I heard an eisenmann race exhaust yesterday and an akropovic and the eisenmann sounded way more bad ass

On what car?

X6m and an m5

^ depends on the Model, not just exhaust.

You have to listen Akra and Eisenmann on same model. Stock F10 M5 vs stock X5 M is big difference. Stock F10 M5 is much louder.

E60 M5 is NA V10 engine and totally different beast and can't compare to TT X5 M or F10 M5.

Got my Akra catless Dp's and Akra Evo exhaust with black carbon tips + ESS catless tune... Install is in 10 days!!

Any video of your install?

New M6 with Akrapovic

:wow:

I will try I upload a few YouTube clips..but no "install" videos.

I'm extremely happy with the setup.

It can be as quiet as stock or if there is a crowd on the street I can gun it and it induces involuntary urination in the masses.

I meant the video or sound clips. ;)

:rofl:

Akrapovic Evo exhaust with downpipes
 

I recently added the Akrapovic downpipes to my evo exhaust and did a MCChip retune.

No errors and no backfiring. The flow is so good you can hear the whistle of the turbos out the back, which I found annoying at first but I'm now getting used to. The note is loud but not as deep as I had hoped for, nevertheless it really screams when I open it up. We put the car on the hub dyno and got a bit of a light show:

i find the whistle a little annoying...i have vigilant hearing and am neurotic about going deaf from the noise! with the car in power mode and fully in race mode with the windows down, your ears will definitely get some sonic exercise!
