Fitted my new Leos today, love em! I decided it would be of benefit to video teh bike with the Akras on and then the Leos so people can make a good comparison with all the same equipment and bike etc....only the cans are different in each clip. I took dB readings for each one as you can see.
he end titles didnt really work, what its supposed to say is allow an extra 2 or 3 dB for boundary effect cos I know the Akras made 102dB at idle in the open so the 105dBc is boosted but the slightly enclosed space it's in.
Hope you like it.
In my opinion the Akras are of a higher quality of build, the audio is almost identical from each, the Leos have slightly more bass but not much. The Leos also weigh more, not sure exactly how much but prolly a kilo or 2 I'd say! Despite the Akras being higher quality I'd say that the Leos are far better value...mainly cos the Akras are such a rip off!
EDIT: I took it out for a spin after fitting and while both cans were popping a LOT today, the Leos were shooting 6" blue flames on overrun which made me very happy.
