Complete Loudness Comparison of all Exhausts

Dudes, I decided to make this post into it's own thread cause I think it is useful information for anyone shopping for an exhaust for their F10 M5. This is just an assessment based on loudness alone, this has nothing to do with tone. I think once more downpipes start hitting the street I'll make a new list.

Somewhere on this Forum Rob///M5 made a really good list of a scale of 1-10 of loudness of exhausts, but I can't find it. I was going to post it again here but I'll just make up my own based on my experience instead. If anyone finds it, please post it. Thanks.

Anyways, after playing with my buddy's Stage 2 E60 M5 a few weekends ago and also hearing my other buddies Straightpiped Lambo Superleggera, here's how I rank the exhausts that are out today:

-Again ranging from 1 (mouse peeping in the night) to 10 (jet aircraft at full afterburner).

Update 6/18/2013: Since the time of this original post several new developments have come about. More people are starting to get Catless Downpipes for their M5's and M6's. Also a few new exhaust systems have come on the market which I have not heard yet., such as the RDSport Exhaust System, and the Vorsteiner System. I will post them up if I ever get to hear them in real life. I have updated the list accordingly.

Update 8/14/2015: Been a couple of years since I've updated this thread. Since then I've heard a few other exhausts, plus at the time of the last update the Competition Package wasn't out yet. I'm adding a few others for your perusal. New additions are in BOLD.

1: F10 M5 Stock Exhaust (Although the crack from the stock exhaust is louder than most other aftermarket exhausts, I think it may be because the stock mufflers are actually smaller than a lot aftermarket ones)
1.5: Competition Package Exhaust (No Baffles) / Stock Non-Competition Package Exhaust with valves wired open.
2: RPi GTS Exhaust / Akropovic Exhaust, Competition Package Exhaust with vales wired open.
3: F10 M5 Eisenmann Sport (Mufflers Only)
4: F10 M5 RPi GT Exhaust / F10 M5 Supersprint Exhaust (Mufflers Only)
5: F10 M5 Eisenmann Race Exhaust (Mufflers Only, this is actually one of my favorite setups)
6: F10 M5 Meisterschaft GT Exhaust, F10 M5 with Turner Motorsport Axleback Muffler Delete Exhaust
7: F10 M5 RPi GTM Exhaust (The Cracks from the exhaust will actually hurt your eardrums though) / E60 M5 RPi GTS Exhaust / AMS Catless Downpipes with Akrapovic Titanium Exhaust.
8: E60 M5 RPi GT Exhaust / E60 M5 Eisenmann Race Exhaust / E92 M3 RPi GTM Exhaust / Sharkwerks 991 GT3 Full Bypass Exhaust.
9: E60 M5 RPi Stage 2 with Full GT Headers and GT Exhaust / Almost any E60 with Headers and Exhaust / Straightpiped Merc C63 / Straightpiped Aston DBS / Straightpiped Lexus ISF / F10 M5 with AMS Catless Downpipes and Full Eisenmann Race Exhaust / and any kind of custom exhaust that is straighted-piped as well. There have been quite a few independent shops that have made custom exhaust sytems for the F10 M5/F13 M6 and some have been straightpiped.
9.5: F10 M5 with Catless Downpipes and RPi GTM Exhaust / Audi R8 V10 with LMS Headers and reduced muffler exhaust.
10: Straightpiped Lamborghini Gallardo Superleggera / Straightpiped Porsche Carrera GT / Straightpiped Lambo Aventador

Great idea to post this list.

The E-Race mufflers are definitely louder than the Supersprint "road" mufflers. I would swap those 2 on your list. Otherwise, looks about right

After further pondering, I concur.

Dave - I think the Eisenmann Sport Axleback is quite a bit louder than the Akrapovic.

Agreed. I revised the list a bit.

Can any of you guys (expert) can reference the drone noise level, if any, onto the above list. I know everyone's perception of noise varies, but a general observation would be much appreciated.

Your'e only going to get drone if you remove the resonators completely. The only exhausts out of all of them that I know of, I could be wrong, that remove them completely are the:

- RPi GT
- RPi GTM

That said I would said that the drone is awesome! It's about a level 3 or 4 out of 10 inside of the cabin. Where as the drone on the E60 V10 was like a level 8 or 9 without the resonators. Plus the E60's drone was all over the rev range, where as the F10's drone is only from 1,600 - 2,000rpm on the RPi GT and you get an additional drone range with the RPi GTM from 2,800 - 3,000rpm. But like I said they both sound good and is livable in the F10 where as in the E60 the drone could get very overwhelming at times. Those two extra cylinders in the V10 make a big difference!

Would adding only E race mufflers intrude in the usual freeway commute? I am looking at adding more bass and sound into the exhaust but not at the expense of normal day to day driving. My heart says that E race would be perfect(as it would not drone and would sound awesome at WOT) , but my friends are recommending E sport + x pipe.

I have had personal experience with the E Race on my E92 M3 (just mufflers) and I loved the bass it added and yet retained the civility during normal driving. Can the same be said for the E race for the F10 m5? I do not wish to fall back on Akra(what a choice eh?) as I already have the full catless akra setup on my M3 and I love that too death as it doesn't drone at all and sounds great to me. If I had to fall back on akra then I would go for their EVO system with all cats retained. But I really want to be sure about the E race. Please help!

The E Race section 3 will not drone at all. Just ask Rob///M5. Besides the sound proofing/dampening is so damn good that even the straighpipe setup is still too quiet. You will have nothing to worry about.

Totally civilized at highway speeds. The only drone is on coast down at around 1800 RPMs. Way LESS drone with the E Race than with the Supersprint "sport" mufflers I tried first (which is totally weird).

Cold start is LOUD. That's the only part of the sound that's "uncivilized"...but kick ass

I love the E race!

Can any of the mufflers with the vacuum valve bypass be controlled via manual mode? This would be equivalent to what I used to have in my C6 ZO6 which everyone called the "man switch".

Where's Turner fit into all this? I have it, sounds great but haven't heard any in person to compare (other than stock). I'm in Dallas if anyone wants to compare. I'll be at Cars and Coffee at Classic on Saturday.

Thanks for the reminder. I have heard the Turner system at Bimmerfest back in May. I have ranked it as a number 6. It is really somewhere between 5 and 6, but I gave it a 6 for good measure.
