Akro Exhaust

Ducati Forum

Help Support Ducati Forum:

So, after speaking with a few dealers, I am being told by some that the akro exhaust is track-only and not street legal. What? Anyone else heard this?
 
Why would you think it's street legal? It removes the cat and and the noise reduction equipment.

My dealer here on EC won't install one unless you remove the blinkers and mirrors and sign an affidavit that you'll only use it on the track.

I guess it was commonplace to have this exhaust installed for a while now along with the similar one with the 959 and I didn't hear about this until now.
 
You're correct and I wonder if it's more than a coincidence these edicts from Ducati HQ came down to my dealer shortly after the raid on HQ. Because there was a more of a wink-wink thing going on before last year.
 
And, according to my dealer, you have to show proof that the bike is registered as non-op w/DMV.
 
Perhaps this is a silly question, but I have seen some V4s with various exhausts, including termignoni and flames shoot at are high revs when shifting, etc. Is this something that can happen with a V2 or is it just not possible? Would it happen with the akro?
 
Its happens when the secondary air injection system is left in plate without the catalytic converters. The SAI forces fresh air in the exhaust after it exits from the exhaust valve. This is meant to burn unburnt fuel. Without the cats, you get the flames and loud(er) pops. So you can eliminate the air injection system with block off plates, or not worry about it.

A bonus to eliminate the air injection is that it can effect air fuel probe readings when at the dyno.

Thanks for this explanation. Really helpful.
So, if a V2 has a full akro, is it possible to have it flame? Does the full akro get rid of the cat?
 
It is possible, but on my 1199 it wasn't as bad as I noticed on videos with the V4. Then again, when I was riding I wasn't really looking for flames. I did have a lot of pops though. On my Streetfighter V4 with the full Akro and block offs I didn't notice it popping anymore than stock.
