Damn Dude, you beat me to it:wtf . I was going to post the same thing:hammerFreak Show said:FROM www.freetranslation.com:
It causes a/the volume regulation a clear, while pursuing exhaust efficiency/ .
It is アサヒナ technical サーレンサー (ATS) that was born from a/the race scene to cause 2 elements that contradict a clear.
The exhaust gas that gathers from the such formation thing, エキパイ that twisted the 仕 earnest board that was attached in edge department after a/the center pipe and passed a/the center pipe is given a/the rotary motion with ATS of edge department after. The turn energy becomes big begin to inhale strong if an/the engine becomes a high turn and indeed, in a/the high speed area and the exhaust efficiency over generate, original silencer underwear diameter are materialized an/the effect.
《主語なし》In the case that an/the engine turn number is low it is small turn energy even, begin to inhale it and there is not the sacrifice of a 速 area while is depended to come off too much, because even an/the effect is small.
And an/the exhaust turning inside, a/the silencer and a/the 消 sound effect increases, because it tries to spread outside by the centrifugal force of while, and can give the effect equivalent to taper underwear in spite of, straight underwear.
For example a/the 消 sound effect is materialized fairly exhaust efficiency and, underwear diameter 50φ fairly underwear diameter 60φ in the case of the underwear silencer installation of 55φ.
oasam said:I'm a japo and per the ad the idea behide it is that at the higher rev, there's a strong negative pressure, which sucks out emission air for better maximum power, created by the circulating airflow at the end the exhaust pipe. On the other hand, at the low-mid rev, due to it's narrow pipe (and also less sucking effect from circulating airflow), it gives a good pressure for better torque.
Also, as you can see in the pic, circulating airflow helps facilitate noise reduction by directing airflow towards glasswool at outerside.
This isn't something new though.
