M5 New Exhaust Advice needed

[M5 Muttley]

Have had the E39 M5 for a couple of weeks now and can’t make my mind up whether to get a new exhaust or not

I just don’t think its loud enough, I want it to rumble and sound a bit like an AC Cobra <<< this would probably be too loud

I am not looking for performance gain, just want the sound
Any advice on what exhaust to get would be really great

Cheers

Dave

Hayward & Scott makes one for around £500 - and it comes very well-recommended. See bm3w.co.uk for some reviews

Tubi Runmore+

I use my Griffith 500 with straight through pipes as a yard stick as to what sounds good V8 wise. I have to say Tubi seem to have got it about right. The E39 M5 is crying out for it. I think BMW could have made more of an effort in the sounds dept. But that's the trouble when they're appealing to the mass market. They could also have made all M3s sound like CSLs at not much extra cost.

Gone Hayward & Scott myself, love it, sounds awesome and you can specify what size tail pipes you want - I went 75mm but some people have gone 80mm. Takes about 4 weeks to manufacture and about 90 minutes to fit .

Have watched the vid to many times now I really like the sound just wondering how much the nieghbours are going to hate me

I need info on price and is it full or part system and what is involved with fitting ..... does engine need re-map ??

Do you have anymore vids of the exhaust ?

How does it sound on moterway ?

As i dont know much about this i need as much help as i can get

Neighbours haven't been too bad, although one old boy popped across the other day whilst I was cleaning the car to ask what was wrong with my exhaust

Fitting is really easy, it's only the rear boxes and pipes that are changed. There's no need for any re-mapping unless you want to do that as well.

You'll be looking at around £500 plus VAT. (Mention you've seen the good feed back on the M5 forum group buy).

Although quite loud it's not too intrusive for motorway driving - most of mine is Motorway. What you will find is that you are driving with the window open a lot more and looking for tunnels or built up areas. As a result fuel consumption goes down as you are forever dabbing the accelerator.

It really starts to wail at about 4k revs especially in 3rd gear and there is often a fantastic popping /burbling sound on over run.

Over on http://www.bm3w.co.uk you'll find loads of info, one of the members "Welsh Willo" did have some fantastic footage. Perhaps you could PM and he'll share it.

This is one of his vids from inside the car.

I only have one other video myself and once again that was on start up. So not really that great.

[M5 Muttley]

Thanks for that peeps

The neighbours thing is a big consern as i have to leave for work on saturday morings at 3.30 and I need to be able to sneek off the estate without waking them up

Liked the bit about driving round with windows open looking for tunnels Heathrow tunnel is only 10 mins from here.
Got a feeling that is the first place i will be going when i make my mind up what exhaust i am going to get ..... To many to choose from

I now want to go to the Isle of Man after watching that vid ..... Car did sound nice

Tryed to join bmw3 forums but didnt have much luck registering ..... but did join forum.bmw5


Oh well back to the research

Dave

its all to do with the resonator
i.e the middle box
the M5 v8 has a pronounced boom which BMW designed : damped out with a huge heavy centre section
Ian @ H&S has two options

1. keep centre section : and run very small back boxes these are 500+vat No remap needed

or

2. go the xpipe route and have no centre exhaust box : much more ummm vrmmm

in the end i went the whole hog

headers / race cats / x pipe and beefier rear boxes than option 1 and a re-map

we saved over 60kgs of weight as well

Think i will be going for option 1
Have spoken to Ian today and he said six weeks wait to get them done
Was also thinking about some custom tips or maybe just large bore standard pipes
I was just looking at your blog and thinking I would like to colour code my car but now sure wether it would look right on a silver M5

Could you tell me how much it cost to get that done please ??

Thanks to all for the advice

Cheers

Can anyone help me cure what appears to be an unresolvable issue with the (standard) Tubi seeming to 'knock' on mine?

Being of bigger bore, it must be nudging th'eatshield or sommat at one or more points along it's length and it drives me nuts on certain types of rough road (i.e. all sections of road these days!).

Is there some kind of bush to jam somewhere because I'm thinking of putting the original back on.

I actually find it a bit boomy when lazy through the gears, maybe the H&S one's better? Worth a punt d'you reckon?

Then again, rather like the whiff of napalm, I do enjoy the melthrob on start up of a morn. {And it's still the best car ever manufactured. }

tubi style do exhausts for you m5

[M5 Muttley]

Hi Peeps

Looks like I will be getting the Hayward & Scott back boxs

At least it will sound more like a V8 then Cant wait

thanks again for the help with this

Cheers

Dave

Haven't got an M5 yet but I have always thought that the likes of Tubi dont really sell anything that special, IMO you are paying for the guaranteed fitment and an exhaust that is loud but not so much so it fails the MOT for excessive noise or emissions.

I was thinking along the lines of this guy on M5board: http://www.m5board.com/vbulletin/showthread.php?t=... Some aftermarket silencers and straight pipes from the manifolds. No resonators, no cats, nothing!

Seeing as I have my own pit I feel happy to spend a few hours a year swapping the pipes to put the standard cat system to pass the MOT. And it would only cost a few hundred pounds for the silencers and a good quality pipes in between...

Or would this destroy the economy and torque, so I would be better off with not saving money and going for a full Xpipe system?

What about a Milltek?
Quiet on tickover, then not when revved...

Come on then do tell, when are you going to place the order ?

[M5 Muttley]

Will be very soon

After hearing what yours sounds like ... my mind is near enough made up.
Made my day that.

Then I will be out tunnel hunting

Cheers

[M5 Muttley]

I spoke to Hayward & Scott today, ordered the back boxs

I just have a possible 4 weeks agonizing wait.

Then it will be time for some tunnel hunting and hopefully meet up again and do a dual video


Cheers
