For those who know the eisenmann race exhaust...

^ so u think i should get into section 2 or even 2 & 3? many have told me that the car will get much louder by doing so. My main point is to get rid of that sudden loudness that happen while in traffic and idle.

Go on m5board and ask this question. I am also curious to know why the car revs to 1000rpm from time to time when idle!

When the cats warm up the o2 sensors raises the idle to compensate something... That's what i remember.

I've had the pleasure to take my cousin's m5 that had a full hamman exhaust system from the engine all the way back. That thing was the loudest thing I've ever driven it was louder than my current v8 which is extremely loud. Hope this helps.

Hey,

I have a question about the eisenmann RACE exhaust for an E60 M5...

Please tell me if the exhaust is very loud, as in will get in trouble every time next to police!

Cant really tell from the video clips and sometimes it is not mentioned if the exhaust was simply the section 3 exhaust or a full system.

For those who know the exhaust or heard it, please give your input.

The car has the Tubi exhaust already, and that is medium loud it seems.

Thanks.

Sorry folks.. just seen this thread..

Sooo.. Eisenmann does NOT produce full systems.. only the section 3 which are the Backboxes... In my opinion nothing sounds like Eisenmann Race BUT it drones at low RPM. I would describe drone as a continous low base noise in the cabin.. Some people even enjoy habing a bit of drone.. But its like always in life.. everything has its price.. so if you want THAT F1 Sound you will have to live with a bit of drone...

But i ve got something else in mind.. you ve got pm.

Okay so whats the solution for this?

Thank you Bruno, bingo!

When I hd my evosport headers ( primary cats deleted and O2 sensors bypassed ), I did not have this issue.

Now that I have installed Section 1, 2 and 3 with stock headers and cats, I have this issue.

Hopefully when I install the decatted Evolve headers, and get it tuned... I can confirm this 100%

^ Hmmm headers on the e60 M5 is a pain to install. I've seen a thread on installation process, God the entire engine has to be pulled out, etc.

Is it that hard to install headers?

So Ahmed, your engine has been pulled twice?!

Nope, anyone who moves the engine an inch to install manifolds is obviously not good enough! I've had my manifold removed twice... one day job!

No moving engine up down left or right.... all you need are 10 new gaskets, and 2 new flange seals!

I have a video of my headers being installed. I can post it!

[LSB_M3]

Great! otherwise i think its too much to remove the engine etc!

[///power]

Why not Ahmed, post it please! Maybe in the DIY section, dunno.

Just saw this post. Not sure I heard people get it only when installing aftermarket sec3 leaving the rest stock.

Extremely Loud! I would recommend as well Tubi, keep us posted.

Like simon says... Get the backboxes... I have had my exhaust since march, absoutely no probs with cops. Its whenyou rev above 3000 , thats when you gotta be careful.. It drones, but trust me, i know members, whom sold their eisennman after 1 week of installing it, only to kick themselves for doing so, because once you install and turn on the engine, the issues of droning suddenly isnt important anymore... The smirk that is on your face every morning will testify to that :).... Rpi is also a good exhaust, although not as loud..
