Brooklands Exhaust Endgame?

Brooklands Exhaust Endgame? - 20/05/19 07:46 PM

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, you'll have to get out of that fair weather club and come join the rest of us loon's soon cheers

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!).

Grab yourself some popcorn and read the thread in this LINK for everything you need to know about Brooklands exhausts!

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.

Thats good you not far away at all! small group of us on here(the Forum) go to The cafe at Blackbushe airport for breakfast meets when there's not much else going on.... always posted on here, cheers drive

Re: Brooklands Exhaust Endgame? - 21/05/19 06:13 PM

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.

Re any welding reqmts - I can recommend Malcolm at speedweld - Farley Hill

He can sleeve and support where needed.

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.

It looks like we might be meeting you at Blackbushe this weekend, we can go through all the chassis and various upgrades with you.

Perfect, but don’t frighten the wife. 🤦‍♀️

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.

Very worthwhile checking...

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?

Re: Brooklands Exhaust Endgame? - 24/05/19 02:56 PM

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.

Re: Brooklands Exhaust Endgame? - 24/05/19 03:13 PM

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.
