Emissions Notice: This product alters a factory emissions control device and does not meet current emission laws. For motorsport use only. Please see our emissions relates modifications disclaimer here.
The MMR Performance high-flow exhaust system for the Mini JCW F56 unlocks power, provides a perfect rich sound quality and improves aesthetics, all whilst giving the driver the option to control the exhaust valve with the push of a button. Available as either a downpipe, cat-back or complete system.
The cat-back system uses enlarged 2.75" pipework to provide a freeer flowing path for exhaust gasses to follow, whilst the carefully designed centre resonator and rear muffler offer less of a restriction compared to the OE system, but still give the F56 Mini its addictive exhaust note.
The addition of an exhaust valve delivers the best of both worlds, allowing you to easily switch between a more docile soundtrack and one that unleashes the true dynamic tone and sound level that's just waiting to get out, all conveniently activated from a push of a button on the supplied key-fob.
Finishing the cat-back system, which can be joined to the OE downpipe as a standalone rear section, are a pair of beautifully manufactured twin carbon fibre trims, complete with MMR logos.
The 3" downpipe removes the native restriction in the OE equivalent, but with the addition of our 300-cell sports catalyst further reduces back-pressure and improves performance. The pipework is coated in the latest heat shielding technology to help keep unwanted heat away from your engine bay and improve exhaust gas speed internally.
The MMR Performance Exhaust System is available as either a downpipe, valved cat-back or complete system and is supplied with everything you need for installation, including clamps, valve motor assembly, wiring loom and two key-fobs.

Mk5 R32 Turbo. I have had the best experience top quality service I would not think about going anywhere else! From helping me install my ecu over the phone with help on wiring sensors troubleshooting I would have been totally lost not to mention the remote mapping service so I was able to fit it in around work and other things the car runs like a dream pulls hard in all gears and is music to my ears. I will not take my cars anywhere else 5* Thank you for bringing my project to life
Something came up that required me to get a car part urgently and under a time limit and I was having trouble tracking down local businesses that could source it for me. Luckily, I came across Sameer’s contact information and reached out. He was brilliant - answered my query over the phone, got the part ordered as soon as was physically possible and kept me updated every step of the order and delivery process. He solved my issue with professionalism and expertise. Very happy with the service received.
Sam always does a quality job when it's comes to mapping my car. It has been with Sam multiple times for mapping, tweeking and problem solving and is very knowledgeable when it comes to ECU masters. The passion toward cars and mapping reflects in his work!
Absolutely great services. Great communication. Always ready to help. My car is now faster, more reliable, and made way more power. Sam is the man.
Great mapper. Have full confidence in him, helped out with everything i needed even when some things were not right with the car. Highly recommend👍
