Was wondering what would be best "for me" between the exhaust kit stage 1 from Morgan vs Garage 56’s kit. So I thought of gathering all kinds of comments, summarize a bit what I’ve heard or read so far.
I share it here as I think it might help others, and feel free to contradict me from your personal experience.

Sure it is a question of taste before anything else, but I think it still might help

Stage 1:
- Sound signature: beefier throatier, slightly raucous, great pop when decelerating (characteristic of higher flow exhaust) MMC Stage 1 has mellowed over the first couple of thousand miles
- Power: gets the power back to the level before fitting urban cooling kit, or slightly higher
- Noise level: louder than standard (not necessary a positive in Belgium), police officers have sensible hears
- Motorways: pretty loud and probably wearing for a long distance ( but mostly wind noise in any case)
- Price: Cheaper option

Garage 56:
- Sound signature: very deep sound
- Power: power diagram suggests it gets the power higher than standard. Comments suggest car has more grunt, more overtaking ability
- Noise level: In terms of noise levels, the G56 Stage1 kit measured within 1dbA of the standard at idle, and +3db at 3700rpm (2/3 engine speed, as per track noise measurement), so pretty comparable to standard (from flatcap racing)
- Motorways: the G56 exhaust actually seems to get quieter at motorway cruising rpms.
- Price: expensive, especially with the ECU module.

Attention: both can be loud:
Quoting Grockle: “G56 but agonising over any extra noise. As you may have worked out from the
blog we live in a very rural location, it is silent. I have visions of the neighbours sitting
bolt upright in bed when I start it on a Sunday morning.. “

WilsonLaidlaw: “I fitted the Garage 56 exhausts along with intake kit and reprogrammed ECU. Transformed my 2012 car completely. My M3W lives in the south of France, where ambient temps can be very high and the pinking even with octane improver and 98 fuel was dreadful. Now totally cured. Only problem is oil temps, with increased engine performance, now above 100ºC. Not a problem for the oil as Motul 300V Le Mans rated to 165º but due to concern about original oil pipes, I am going to replace them with B F Goodridge 200-08 braided steel covered nitrile pipes, rated to 150º. I will get this done (with me supplying the pipe work) when it goes into RD Racing at Le Castellet to have the chassis check and strengthening done, comfort steering kit fitted, new type Centa Compensator, new type rear hub with lightweight steel sprocket and a full service.”
