E92 M3 Akrapovic Evolution Exhaust

[TheJusticeCross]

3XX hp ? BMW says 420 !

I think that the new 6.3 AMG is also a good singer, C63 AMG sound is good. And this akrapovic too. But BMW > Mercedes.

[iTouchHelp100]

@TheJusticeCross 1. ahaha 420

2. c63 amg is a nice singer and has an amazing sound

3. i agree bmw > mercedes

:D

[1995BMWPOWER]

sounds amazing !!!

love it

[cinayet36]

You must turn the power button on, you will get the max. power!!!

[xXNinjaTunaXx]

this is louder than stock though right?

[ervinski7]

only with exhaust 334 whp ?

[Ivannos92]

wait! the on the wheels it has only 318HP! i thought it would have more than that, at least 360

[siddarth649]

turn the power button on...you'll get 450hp with the stock exhaust!

[marvrage]

I love all the stupid comments in here... why not 400+ HP??? Why not learn a little something about cars and tuning before you comment.

[lethaldosage6040]

since I cant afford a dyno test, maybe all you fine people can guesstimate as to how much power my car has. Its an 08 Mustang GT with a 93 Bama tune, Longtube headers, ProChamber, and axlebacks. Oh, and a K&N air filter (not CAI)

If i could afford a test, i wouldnt be asking for ideas on this matter

[ASA1689]

This is a gintani video production :s

[1000RRboyJay]

sounds ace

[marcsigi]

the m3 has as fabrication data 420 hp why only 300 on the dyno ?

[imhypoglycemic]

@marcsigi A lot of people don't realize that manufacturers provide horsepower at the "crank", or what the engine produces. A DYNO gives you horsepower at the "wheels". There is generally a 15-20% (approx) loss of horsepower in any drivetrain.

[odracirseraoseia1999]

@imhypoglycemic In that case we should be seeing, with the stock exhaust, 357hp (for a 15% loss) or 336hp (for a 20% loss). Instead it read 318hp, which is only 75% of the 420hp BMW is advertising (25% loss). So my question is... WTF??

[imhypoglycemic]

@odracirseraoseia1999 That's why I say "generally". (25% is acceptable IMO) Unfortunately, dyno's and HP or RWHP are not an exact science. That's why you see some guy's ask "What kind of Dyno did you use?" Dynojet? Superflow? Mustang? etc... Whichever dyno it is, they are really helpful in "tuning". I hope this helps.

[vdvpj]

Check out the 2010 M3 w/ Akrapovic exhausts, AP Racing calipers, .. on my channel!!

[JVL8701]

what happen if i put akrapovic bike exaust on a car....

[xkalexanderx916]

omgggg sexy sexy sexy my new porn for the night !! wooo

[idbrown99]

sweet setup man, good choice on the exhaust..

[JeffroGymnast]

Woah. That torque curve is a freakin ruler! Is the torque still good under 3k rpm?

[VLCquique]

Vamos a ver esque una cosa son los caballos del motor (420 segun fabricante) y otra cosa son caballos transmitidos al suelo, o dicho de otro modo caballos que llegan a las ruedas... La diferencia se quedan en la transmision y varian mucho segun el coche sea traccion trasera, delantera o 4x4, creo que me he explicado.

[mkrmec]

still can't belive Akrapovič is a Slovenian firm hehe and I'm slovenian :D... Very nice sound with Akra vs the ugly stock sound...

[aljaz55]

Well, not really big difference in HP. Even bigger difference can be seen between winter and summertime. But has nice sound.

p.s. Akrapovic is almost my neighbour :)

[suprattmtfkr]

so base run was 318.2rwhp with 221.41rwtq huh

i mean wtf, it is rated at 414hp to the crank and it lost 96hp traveling down to the wheel? thats about 23% lossage through drivetrain.

even AWD layouts lose 18-20% at the most for 90%of time.

am i missing something here? plz some one help me out, im confused.

[ForceFed7]

@suprattmtfkr

This was dyno'd on a DynoDynamics. They will always read lower than any other dyno. DynoDynamics read lower than a Mustang Dyno, which reads lower than a Dyno Jet. This M3's numbers are spot on. My buddies 425 HP E39 M5 dyno'd ~324RWHP on a DynoDynamics here in NC>

[suprattmtfkr]

@ForceFed7 ic thank u for info. :D

[patrickh499]

it have 420hp stock.. right?

[mkos021]

sLOVEnia akrapovic power

[DonMacillo]

dude i love this oneee (Y) the sound is veryyyy nice :D

[06pontiac]

nice

[ivanciclonic]

deberia de sacar 420hp de serie

[blackaneeese]

that sound is amazing

[hayes490]

looks like fake results

[Kapitalist88]

@hayes490 : why?

[SpotterGijs]

Sounds fantastic with the Akrapovich exhausts

[radost0514]

ooff on dyno your car is -20& hp becouse its on wheals hp

[Ottakringer]

Is there an akrapovic exhaust for the 09 z4 sdrive23i?

[Nixxomatic]

Not to my knowledge. For cars, he only makes exhausts for the best motorised versions, like the M3, M5 and M6 and the Porsche GT3, I think. I believe he is curently working on (maybe it has already been finished) on the GT-R.

[ElTyranto]

doesn´t this car have 420 HP stock?

[shircle]

yeah, but they're measuring wheel hp instead of brake hp which is what the manufacturers measure. wheel hp is always less, although 100hp seems like alot. i thought it would've been more like 350-360hp

[ElTyranto]

if the engine would have 420 HP it would wonder me if it had less than like 380 at the wheel

o_O

donno

[torxMonster]

No , this is about right, its bout 20% drivetrain loss.

Plus a car moving with proper air cooling makes a difference as this M3 uses a Ram air effect from the factory..

[d3llaha]

just watched Eisenman exhaust on m3 before - i liked this more - becuase of it's kinda electric notes!

[stylinexpat]

Are the gains just from the exhaust or other mods as well? How do you like that exhaust so far? Any problems? Any CEL ?

[Akara316]

Yes, these gains were from the exhaust alone. I love the exhaust, perfect sound, not too loud for daily driving. It will trigger the CEL, but Akrapovic is working on a solution.

[stylinexpat]

That is what I had heard on the CEL from others. You get power loss with the CEL on.

[ahmedbelkady]

yo..where are the 420 horses gone? i mean the 335is can smoke you bro..:S:Snot gd not gd at all..sell that shiit

[gig049]

OMG

[apsexy22]

standard 6.2 liter amg v8 in c63 sounds better w/o any mods

[hbplaya]

@apsexy22

Standard E60 M5 sounds better than any Mercedes has ever sounded.

Anything else?

[Kando0615]

@hbplaya hahahha in your dreams any AMG sound beats the crappy buzzing M5 sound

[scubywrxr]

I jizzed all over my keyboard :D

[straightsixM52]

don't worry you are not alone. Me too ;)
