Hi, any info please, I?ve got the akra stubby exhaust on my 2020, but it still sounds fairly tame, was going to fit matching headers but I?ve been told it needs setting up or will run too lean and cause damage which I don?t realy want to do, sooo has anyOne removed the servo cables so the butterfly stays open, just want it to have a bit more bottom end growl instead of sounding semi electric, would the servo being open permanently cause it to run too lean at bottom end? Any info would be great thanks
