Hello I was thinking of building a Scorpion exhaust to my CB125F. The reasons for this are that I a) already have problems with a strongly rusting exhaust, b) I just don’t like the sound and c) would not hurt a little more power. According to Scorpion, the exhaust brings about 1.5 hp more power, less weight and a much deeper sound. There is the exhaust either with E number or without 150€ extra charge. Is it really ok for whom the bike has more horsepower and is lighter than in the papers who is an E number? Must a software update or something like that be recorded? I have many questions and hope for an answer. Edit: I think it’s smarter to link the exhaust I mean.http://scorpion-auspuff.de/…B-Killer-EG-ABE-E-No-E-Identifier.html
