My mate has just ordered a new E92 M3, and he has read online about :
Backbox cut open wadding removed and perforated pipes wrapped with exhaust sealant and tape. Dead quiet inside and lovely outside, how standard should have been. #exhaust #m3 #e92 #v8 #car # power #performance #sound #modified
LINK ON YOU TUBE SHOWING RESULTS:
Can this be done to the Standard 1M exhaust? Does anyone know if it even has Perforated Pipes to silence it?
I had an accident in my previous M3 and the insurance wouldnt pay out because I had changed the back box to an EISENMAN system, just wondered what could be done with the standard box if any?
