Standard Exhaust Info on 1M
Hi guys,
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? cheers

I guess that means that you hadn't informed the insurance company about the modification - insurance will pay out so long as all your mods are declared, so no need to stick to the standard exhaust (and technically you're talking about modifying it in any case ;-) ) if you don't want to just because of insurance...

My buddy did this mod to his OEM M3 exhaust, except he had them cut out the perforated pipes and weld in solid pipe. The car sounded like a beast. It was also loud as f_ck! Although the sound was amazing outside the car,
the drone inside was so bad under 3,000 RPMs it would literally make your ear drums itch. I'm not sure you would get the same sound, volume, or level of drone from the N54. |

cheers guys, yeah i just found some of the insurance companies got confused to what I had done, and either refrained from covering/quoting me or put a silly increase. So without causing upset to some members, what's the best option for a back box? I want something quite loud, but not silly inside as I do a fair few motorway miles. I had Eisenman before and thought it was good?

I have the Eisenmann Race mated to the N55 and it sounds great. It has a nice metallic crescending sound as the engine climbs the rev range. In addition the fitment and quality is very good with a nice slash cut tailpipe design.

So, if you spot a 1M with an Akra exhaust and there is smoke coming out of the outer tailpipes, the valve is open (or the blocking plate was removed if the car is not equipped with the optional Akra wireless kit) + you will notice a louder rumble. A kind of Dr. Jekyll and Mr. Hyde system. Useful if you got to tone down in sound sensitive areas or when you're not in the mood for a more sporty sound. ![]()

HMS exhaust has the flapper that opens similar to that of Akrapovich
I am really itching to get it for myself... If only the shipping was more reasonable |
