Price increases

Deeper pockets are now required to buy the new EU compliant M3W. Its luxury car pricing  without  luxuries. Fancy a mudguard? That will be extra sir..

No Morgan M4W

So it seems dogs were let into the Run For The Hills event 2017 at the Malvern Showground. We are too far away to have taken the risk. Grrrr..



King Harry & Morgan Three Wheeler


Narrow Streets and Cobblestones

M3W Sea

Normally we will drive miles out of our way to avoid paying a ferry or navigate tiny Cornish streets. In the Morgan, not so much. Its another thing you can do in a Morgan without people minding too much. (Even with the Stage 1 soundtrack) This is the King Harry Ferry near St Mawes.


More Lost Parts

I found the large grommet fitted to the compensator housing (detailed earlier in the blog) has vanished. Maybe it is just as well. I won’t be refitting it.


The Missing Stage 1 Video


Aero Racing Stage 1 – Battle of Britain Simulator


The sound of the factory Aero Racing Stage 1 is of secondary importance. Opinions offered on the subject are often so diametrically opposed that you are left wondering if they are even talking about the same thing.

Of course we all perceive sound differently but paying good money to drive around in a car that sounds like a bag of spanners would have been a disaster. Luckily, it sounds like 1940.

(Turn the volume up.)


Two Stage 1 Morgan’s in Crackington Haven this bank holiday weekend caused quite a stir. Its always nice to have visitors and it was nice to meet up with Tim, all the way from St Albans.


Widemouth Bay Cornwall

By the time we had finished lunch a crowd had gathered to watch our departure. A photo opportunity at Widemouth and then along the Atlantic Highway to Bideford where we said our goodbyes before leaving for home in opposite directions.

GoPro Audio

The MMC Stage 1 overloads the GoPro external mic input when mounted in the usual position but I am working on a fix.

The Garage 56 Stage 1 sounds more civilised than the factory version. It is beautifully engineered even down to the G56 logos cut into its MAC truck heat shields. But you can buy a lot of earplugs with the extra £600 needed to buy it. (£1500).

S&S Outerwear Pre-Filter


Rain sock


As I hadn’t been able to locate a rain sock for the S&S filter in the UK I was hoping that the 2017 forecast for Devon and Cornwall would be less wet that normal. In this part of rural England a high percentage of farmers vehicles are fitted with snorkels so a drought is unlikely.

Then an unexpected and very generous goodie box arrived from the US containing, among other things, the allusive sock. (It rained during installation)

Nice people often own a Morgan.


Blog Traffic


The number of views this blog gets has doubled each year and often visitors come from the most unlikely places. For some unknown reason the Rolling Thunder Tour video still gets over 200 views a week on YouTube. Ok, not as many as the poodle on a unicycle but then the Morgan is pretty niche.

It is strange that there is so much interest in this very British quirky car. Thanks for all the emails, I hope the replies made sense. The maintenance item below covers a lot of them

MMC AR Stage 1


MMC Aero Racing M3W Stage 1 

Legality and Insurance 

UK law requires that vehicle exhausts must not be altered or replaced in a manner which increases the noise above that emitted by the type approved exhaust fitted by the manufacturer.

One advantage of the MMC Aero Racing Stage 1 is that it is an OEM factory option fitted to cars on the production line and in theory at least, covered by the M3W type approval.

Being able to say with hand on heart, “this is how they leave the factory..” was a major purchasing consideration. The factory connection also meant there were no issues with insurance and more importantly, no additional premium.

The kit is similar in quality to the original, constructed from stainless steel and weighs about the same. The pipes are shorter than the classic slash cut versions and terminate in a squared off tail pipe with rolled edge.

The shorter pipes give the car a slightly more aggressive stance but would likely go unnoticed to a casual observer. Although they are well made both of my examples leaked at the manufacturers bolted flange. (See below)


Fitting overview

Fitting is straight forward but alignment is critical to maintain heat shield clearance and avoid early bobbin and/or exhaust failure through pre loading. With care the larger silencers do fit inside the heat shields without modification. A blog entry detailing these issues ended up too long to be included here but I am happy to email a copy (Seven page PDF) on request.



On top of the cost of the Stage 1 expect to pay an estimated 3hrs (£225) labour to have it fitted. A pre 2014 car will require new brackets and heat shields (£375) and specifying a Stage 1 on a new vehicle will add £1200 to the build inc tax (April 2016 price list).

S&S Stealth


S&S Stealth air filter

Included in the MMC Aero Racing Stage 1 kit is a £260 S&S Stealth air filter. S&S make bold performance claims for their filter but how much of it can be attributed to filter design and how much to the removal of a restricted system is anyone’s guess.

The muscle cover is an odd design but well made, easy to fit and looks good.

Initial impressions

Click video

Noise is subjective. Passengers taking their first ride in an M3W with classic slash cut pipes will often comment on how noisy the Morgan is, the Stage 1 is no quieter.

The thin sound of the classic slash cuts has been replaced by a deep rumble that thankfully mellows as the engine warms up. It’s a unique sound that is hard to describe. At the risk of sounding stupid, a twin cylinder V8 seems to cover it. (checkout the video above)

In spite of the jungle sounding intro the video was not filmed in the Amazon. The Sony HD camera has limitations due to its built in AGC automatically adjusting Devon wildlife and the Stage 1 exhaust to the same level. (but at least sound reproduction is accurate.)

Stage 1 M3W

Added Theatre: Winter Job No 10


New Options list: Aero Racing Ltd Stage 1


My M3W with Aero Racing Stage 1 fitted – S&S Stealth filter and Muscle cover

Morgan will happily build you an expensive epilepsy inducing dogs dinner of a car from it’s newly expanded options list. It seems the urge to order a car with a gypsy caravan theme is strong in the some parts of the world and Morgan plan to capitalise on it.

There are two items on the expanded list I would have ordered had they been available in 2014, the rear mudguard, (now fitted), and the stage 1 kit.

Clatter clatter.. 

There are some very cheap ways to improve the running of the S&S engine. All that is required is the inclination, a bit of time and effort and a realisation that there is a strong possibility your Morgan will end up sounding like a bag of spanners and cease to be road legal.

Aero Racing Stage 1

Avoiding the cheap route and to protect the Morgan’s warranty, appearance and legality it was decided the Aero Racing Stage 1 from the factory would be the best option.  Morgan parts rarely work out cheaper than third party equivalents but in the case of my 2015 vehicle the Aero Racing kit was £640 less than the nearest (available) alternative.

The downside to the Aero Racing option was the four month wait. Four months to deliver parts? How is that even possible?

Fitting of the Stage 1 is straight forward but alignment is critical to maintain heat shield clearance and avoid early bobbin and/or exhaust failure through pre loading. I was going to cover the fitting in a blog entry but at seven pages it became a guide.  I am happy to email a draft copy on request.

Oil Tank gasket fails (again)

The oil tank cap gasket has failed again. It seems to last a year before swelling up and tearing itself free of the retaining bolt. The new version includes a larger washer.


Mincing about: M3W winter job No 8


Two Tribes


The pedals in the Morgan Three Wheeler unbolt and move to suit various sizes of driver but it’s not a practical roadside exercise. Adding a bolster to move the driving position 4″ forward to accommodate a shorter driver is (maybe) an option for domestic harmony.

The foam was cut to size (eBay) and leather for a slip cover sourced. Storing it may be an issue on a fully loaded run but we shall see. Seatbelt extension is also required.

Maybe winter job number 9 should be a luggage rack?
