Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Brooklands Exhaust Endgame?

Hi IMHO, welcome to the M3W Brooklands ownership fraternity!

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!

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

It was £500 plus VAT

Thanks Chris that’s good to know.

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.
