Greetings all from a newbie,
I’ve been following this superb forum for a while and was hoping to make the Brooklands meet last weekend but my forum membership wasn’t live so I couldn’t find out where in Silvermere you were meeting up, in the end it looked like rain so I didn’t go on spec. (Yep I’m a fully paid up member of the fair weather motoring club)
I’ve just bought a M3W Brooklands (11/50) and live in North Hampshire UK.
Have to say I’m loving driving the M3W and the wife is happier now I’m off two wheels!
Looking forward to meeting some owners at some point.
Currently trying to get my head around essential “upgrades” the following are done
Cooling fan
All timing belt mods
Rear mudguard
My eyes are wide open so to speak and I’m particularly interested in how the Brooklands exhaust problems got solved as my M3W only had 350 miles on the clock since first registration in 2015 so i’m certain to be finding a few issues and the exhaust cracking seems to be a matter of when not if?
All advice greatly appreciated.

Welcome IMHO and hopefully we'll meet up sometime soon.

You are right in thinking the Brooklands exhausts may well crack at some point but until then the main thing is to get out and about as much as possible and get some (s)miles on the car drive

MMC did come up with a "final" fix involving beefed up mountings and a flexi joint but I've not heard how succesful that's been longer term. If/when they do crack then an option would be to get an independent exhaust company to weld them up - there will be plenty of advice forthcoming from the TM team......

Yup, a good set of motorbike waterproofs and a helmet with a full face visor will see you through almost any wet weather (one in a hundred year New Zealand torrential downpours excluded!).

Got the popcorn and read the entire Thread. Going back for more popcorn to find a good source of the flex joints. I know that Mini Cooper uses one in its exhaust path and I am sure others use a flex joint. I am hesitant to try and get them from Morgan since the communication and the international tariffs would make them more hassle than its worth.

Maybe popcorn and a good single malt to make the search more palatable.

Whats the O.D. Of the current standard pipes?

IMHO, I think it only reasonable to ask you to stay away from sharp instruments and hand over your belt and shoe laces before you get to the reading.....

Skullmog, i’m Just below Farnham, however unfortunately next week i’m off to sail my boat.

BOAT = Break Out Another Thousand, and since my other hobby is my 1971 Norton Commando you will probably deduce that I frequently sacrifice myself on the altar of dubious “engineering” and you’d be right.

Wow what a saga on the Brooklands exhaust, ran out of popcorn. I see there’s a new support bracket arrangement so i’ve Contacted MMC to see what they have to say about the logic? I think i’ll then go see a specialist before making my move, there’s one called Magnaflow near Heathrow that looks interesting.

One issue with the 'new' MMC solution is that one of the lower mounts sits below the level of the undertray, around midway along the wheelbase. This can cause problems with ground clearance when traversing speed bumps. crazy2

Blackbushe sounds perfect Skullmog; close enough to dash for home if someone spots a rain cloud mid Atlantic 😉

Thanks for the info Andy, as our local council have turned our village centre into a tank trap (obviously fearing an invasion of some sort) any reduction in ground clearance would see me restricted to my drive.

IMHO, in reality exhaust cracks are not the major issue.
Grab another box of popcorn and read "Chassis Cracks - lower front Wishbone" and "Cracked & Bent Chassis" on this great Forum.

Be Safe good Sir.....

Hello OZ 4/4, thanks for the link, i’m trying to work out what improvements my M3W has and doesn’t have. It’s 11/50 on the Brooklands spectrum which is quite an early number but it was first registered in 2015 which is very late. I can see I don’t have the gussets welded in on the lower wishbone joint which I thought happened in 2014? When I’m home at the weekend I’ll do a frame inspection to determine what stage of mods (if any) it was subjected to during build.

2014 onwards cars have the improved chassis, with the welded in brace behind the engine. The lower wishbone mount cracks have only appeared on earlier cars, mine was one of them as far as I know these haven't been seen on post 2014 cars as the tube wall thickness was increased on the vertical tube where the wishbone mount is welded.

Hi IMHO, welcome to the M3W Brooklands ownership fraternity! wink

My car (#33) was delivered new in the summer of 2104 and its chassis is the full 2014 version (however the bodywork is pre-2104, no louvres at the back. Go figure …)

Regarding mods I have done … none! So far so good, with close to 20.000 kms made (I think that's about 12.000 miles)

I haven't upgraded the exhausts yet. Somewhat amazingly my domestic solution has been holding and I will keep it that way until it finally cracks, whenever that may happen.

This domestic solution, as explained/documented/photographed in other threads, consists simply in adding a second flexy joint right in front of the silencer. I did it as an experiment while waiting for a new set of exhausts to be delivered (along with the new mounts), and when they finally arrived, after long consideration, I opted to keep them in store just to see how long my "solution" would hold. Testing is, therefore, still in progress.

One other reason for me to refrain to install the upgraded exhaust mounts was the infamous ECU flash that Morgan doesn't care to explain. I have been told here that this "flash" is supposed to make the engine go smoother, but that comes with a cost of "grunt" level that I'm not sure I want to pay. So … domestic solution it is.

I hope you have lots of fun with your car, mine just keeps on giving, even if I can't use it as much as I should. Cheers and safe journeys! smile

Hi MarioCP,
Many thanks for that, i’m Inclined to do what you did as a precaution. I’m told the new brackets reduce ground clearance which I’m not keen on as I am surrounded by speed bumps.
My car also has the older body work (no louvres) but I haven’t yet confirmed which chassis. I’m hoping it’s got the full 2014 as it was first registered in 2015 but it’s the fact it’s 11/50 that’s puzzling me?

All 50 Brooklands were build on 2014 chassis although some weren't registered until 2015.

At the time you could pay extra to pick the serial number so they weren't necessarily registered in sequence.

Hi Chris. That's true, I do remember being faced with that question by Nick Baker, but I don't remember how much it was we had to pay for the privilege of picking a number.

It's a funny thing because my first pick was #50 (my age at the time), my second pick was #27 (Villeneuve fan) and since neither was available I didn't care for it. However I do remember Nick saying most interesting numbers were already taken and that included all the first 10, the #20, #30, #40 and #50, and also the #11, #22, #33 and #44.

So I didn't care, only to later be surprised by delivery of the … #33 car. LOL

The S&S EasyStart Cam Shafts have a compression release mechanism built into them that operates at start and it creates a very similar noise when in operation.

Well, the exhaust cracking has finally started on the near side at the front of the can. Only 2200 mikes on the clock. Well done MMC.
After careful consideration I’m fitting a flexible joint in front of the cans and passing on the MMC fix of a third can support as I don’t see what that has to do with the problem. Making the can more rigid with the front pipe being pushed around by the engine makes no sense to me. I remember an old friend telling me that if glider wings didn’t flex they’d snap off.

Just a word of caution. I helped a friend with trying to sort out his Brooklands exhausts when they started cracking. To cut a long story short, we re-welded the cracks, incorporated new gussets to strengthen where the pipes meet the box and fitted flexible sections just forward of the boxes. It didn't work and we spent a significant amount of money and time finding this out. Once they start cracking no amount of welding will sort them out - it just moves the point at which they crack. The solution was to take the car to an exhaust specialist and have them fabricate a new system similar to the original design but incorporating the gussets and additional flex joints. They were critical about the way the pipes had been joined to the boxes so also improved on these areas. The work was completed in one day, cost £600 (cash no questions asked) and so far seems to be holding up well. They sound good too!

Fair point Bunny,
I’m talking to specialists called Magnaflow and will probably go with what they recommend.

I've got # 36/50 and recently had my exhaust split, luckily I have a welding wizard just down the street. Seems to be holding up for the time being. Love to her how it goes with Magnaflow, I've used them in the past.

Will Magnaflow produce an exhaust that has the same appearance as the Brooklands system? If not you may as well go with one of the more tried and tested systems such as G56, MMC or Krazy Horse. A shame if you go that way as the exhaust is the main distinguishing point, after that it becomes a green M3W with badges rather than a rumbling Brooklands. I believe the MMC "final Brooklands upgrade" is no longer an option, your choice may be limited.

I plan to keep a Brooklands style exhaust, I’m not bothering to talk to MMC and I’m not at all surprised to hear that their so called upgrade is no longer available. Fingers crossed that Magnaflow rise to the challenge. I’ll post the outcome.

After careful consideration I’m fitting a flexible joint in front of the cans and passing on the MMC fix of a third can support as I don’t see what that has to do with the problem. Making the can more rigid with the front pipe being pushed around by the engine makes no sense to me. I remember an old friend telling me that if glider wings didn’t flex they’d snap off.

Just a word of caution. I helped a friend with trying to sort out his Brooklands exhausts when they started cracking. To cut a long story short, we re-welded the cracks, incorporated new gussets to strengthen where the pipes meet the box and fitted flexible sections just forward of the boxes. It didn't work and we spent a significant amount of money and time finding this out. Once they start cracking no amount of welding will sort them out - it just moves the point at which they crack. The solution was to take the car to an exhaust specialist and have them fabricate a new system similar to the original design but incorporating the gussets and additional flex joints. They were critical about the way the pipes had been joined to the boxes so also improved on these areas. The work was completed in one day, cost £600 (cash no questions asked) and so far seems to be holding up well. They sound good too!

Bunny, can you tell me who did it? Magnaflow are too busy! Thanks

If you are thinking of getting a new Brooklands style exhaust made it may be wise to look at a better design for the internals, rather than copy the rather poor design of the original. The shape of the Brooklands system should mean that the internal pipes are one above the other, not a perforated diagonal joining the two. This may be part of the problem with the system? The "final" Brooklands upgrade does seem to have fixed the cracking problems and is worth looking at if you are fabricating a new system.

Planenut is right, the Morgan Brooklands system does have rather unconventional internals. It does sound quite good though!

I bet the Brooklands Museum would be able to give advice on how the internals should be configured.

Bunny, could you possibly post a photo of your new Brooklands exhaust system? I’m going to have one attempt a lengthening the life of the original and then I’ll go down the replacement route.

Did you look into the front pipe entry into the can? Does the pipe fully enter and have a weld to the inner pipe as well as the can or is it just butt welded to the can outer?

The guys at P D Gough were critical of the way that the original pipes were welded to the front and rear of the boxes. So on the new ones, they belled the box end plates and extended the pipes a few cm into the can before welding which produces a much more robust joint. It does result in the internal oblique perforated pipe being a little shorter but this doesn't seem to have any detrimental effect.

These photos should give you a better idea of what else was done to strengthen the original design. (Sorry it's taken a while to post the photos.)

After a whole lot of contemplation I decided to give MMC the opportunity of fixing this problem. The guys at Malvern have fitted two new Brooklands exhaust rear sections along with new three point mounting brackets.
The construction of the new exhausts appears to be stronger at the connection between the front pipe and the can, I’m not a sheet metal expert but I’d say it looks to be swaged and then welded - much tidier than before - I guess time will tell.

I have comparison photos and if you are interested and can post pictures on TM then PM me your email and I’ll send the photos to you.

Total cost £2.7k spend

£2,700 to replace something like an exhaust seems a little bit much to me but you seem happy with it so..............

“Happy” would be a free of charge fix for a well known latent defect. But as often is the case, low usage before the end of the warranty / defects liability period saves MMC.

On the positive side of things, you now have what looks like being the final answer to all the Brooklands exhaust system problems, the fix that it should have been in the first place if correctly designed. The owners that have this specification of Brooklands system have not experienced any further issues with it cracking, to my knowledge.

The only problem is the slightly reduced ground clearance of the mounts, watch out for speed bumps! You can justify this expense with the man maths that your limited edition Brooklands M3W, complete with sorted exhaust, will probably be worth more than the average M3W, if you should ever sell it.

That’s my hope, I’m certainly pleased with the structural design of the new exhausts, however there’s suddenly major resonance as the revs fall past 3500 rpm that is trying to shake the support brackets apart. doh

Stiffer brackets with more clearance on the can should reasonably contain it but I’m wondering if it’s a function of the can Internal’s?

You could do worse than fitting some support brackets as pioneered by Obie.

I like that! My car is going back to Morgan today to have some improvement to the bracketry, I’m really hoping they don’t just cobble about with the existing bad design.

Obie's brackets are great esp with a heavier exhaust system (we have the G56 one)...and save the regular re-riveting of the side panels required before we fitted them....

The saga may be over?

My car has just arrived back from MMC with its 4th Brooklands exhaust. The sequence went like this -

👉Original exhaust cans cracked at about 2500 miles.
👉A new system with the three point support was purchased by me and fitted by MMC. The new brackets were shockingly bad (see previous post) and MMC tinkered with them but didn’t replace them.
👉The new system cans then cracked after just 300miles
👉MMC took the car back and fitted proper brackets with a loan exhaust while they completely re-engineered the silencer assembly over three months.
👉The car now has the “all new” system fitted. It looks like the original but has the three point support for the can and I am told is totally re-engineered internally with better quality materials.


Time will tell, but I am pleased that Mark and his team finally bit the bullet and took the past failings seriously enough to start from scratch to produce a nice looking exhaust with a great sound. drive

It’s the same 3 point mounting (“upgrade”) as shown in the parts book, sorry but I’m rubbish at posting photos on here, i’ll give it a go when I get a chance.

I spoke way too soon.

The new brackets are awful, the can vibrates against the body and the heat shield, the bobbins are not supported properly and the header nuts have to be slackened off to push the bobbin studs into their respective bracket slots (the exhaust tube clamps are hard up against their shoulders).

It’s going back to Morgan for the fifth time, that is when they can fit me on a back load as it’s “uneconomical to specially come to pick up my car” (their words). banghead

The exhaust brackets on a Pembleton are a half round support on which the pipe rests, just in front of the silencer, with an expansion spring over the top (just like racing cars of old) this spring allows for engine movement and for pipes to expand & contract lengthwise.
These have proved trouble free on my car over 15,000 miles.
Might be worth copying?
