Does anyone have any ideas for an exhaust upgrade for my 2022 S All4? I had a Borla on my 2012 and I have one on my wife’s cooper s convertable, but they don’t have one for a countryman gen3. I can’t seem to find one fro anyone at this time. Any help would be appreciated.

 

Seems to be one of the best solutions.

Remus Countryman Exhaust

 

I installed NM Engineering exhaust on my F60 All4 S. Love it.

 

Make that two votes for NM Eng.

 

Did either of you notice any increase in performance with the NM?

 

Any sort of droning or loudness when cruising at the 70mph range?

 

The only way to really know is timed runs...which I did not do.

 

At 70, I don't hear any exhaust sound...unless I'm still accelerating! I did a 10 hour highway trip this past weekend, and it's not an intrusive sound to my ears. I have a JCW, which is known for it's pops (pre-2020, when they bumped the HP up, but, cut back on the over-run pops). This exhaust will REALLY pop and burble on over-run deceleration. If that is not desired, keep it out of sport mode and it's MUCH less. Keep it in Green mode and it doesn't pop at all.

You lose the flap that covers one exhaust outlet (if you had it on the OEM version). So, the exhaust sounds similar no matter which mode you are in...except on deceleration. RE: that flap...I unplugged mine, taped it up, wrapped it up in a ball with more electrical tape, and secured it up high in the undercarriage to try and minimize any chance of water ingress. That was over 5 months ago. No codes ever thrown. Not that I expected there to be a code due to perhaps a slight change in backpressure in the exhaust, but, I didn't know how picky the computer system is...I mean, could a sensor tell the flap motor didn't work? Apparently not.
