For a pretty penny too... I bet the sound is amazing from both

 

Personally, I don't think my car actually drones. I've heard some bad exhaust jobs, and at highway speeds the tone resonates and seems to turn your brain to mush. In my car, It's just louder than normal.

Now get this. This will sound counter-intuitive, but once you remove all of the fiddly exhaust bits, Green Mode is louder than Sport Mode. Let me explain.

In a stock JCW, Sport Mode changes the ignition and valve timing along with throttle mapping to help the car produce as much power as possible. Then, the ASD module creates some artificial exhaust sound and plays it through the speakers to give the effect of a louder exhaust. In Green mode, the same stuff happens for the opposite goal, being fuel economy. Except in Green Mode, no artificial sound is created. In stock form, Green Mode is the quietest mode.

Now, when you remove the catalytic converter, resonator and muffler, the exhaust obviously gets louder, but what I've discovered is that the tone that Green Mode produces in a straight piped exhaust, because of the varied timing and engine management, is very harsh and does indeed drone quite a bit. However, in Sport Mode, the tone is much less abrasive and is noticeably quieter. Of course, the ASD module is still working away creating that artificial exhaust note, but there's no way you'll ever hear it over the sound of the actual exhaust.

I made this discovery on a road trip from Kansas City to Chicago when I had the cruise set. In Green Mode, you'll get the best fuel economy, but the drone will drive you mad. With the cruise set, you can flick the driving mode switch over to Sport Mode and instantly hear the exhaust volume be cut in half. It was quite surprising.

As a side note, when driving in Mid Mode with the cruise set, the Green Mode engine telemetry is applied for better fuel economy. Switching from Green to Mid while the cruise is on yields no acoustical difference.

 

Yes, but they sound awesome.

We should have Garbino exhaust here very soon.

 

Remus is awesome. Just got back from almost 8,800 miles that included MTTS West (I live in Florida). Installed the Remus exhaust on my JCW and it was awesome. Observations:
- a bit lout on startup ... not an issue for me
- really nice idle sound
- lots of options ... great capability, but I keep mine 100% open ... always defaults to last position
- plenty of bang and pops, but not obnoxious
- no drone whatsoever at highway speeds ... even fully open

I got a lot of positive comments on the sound ... it really is nice. Best of all worlds ... super idle sound, great sound on acceleration and deceleration, but totally quiet on the road.

Could not be happier!

 

Do you have an AT car? This sounds exactly like sport mode was keeping your car out of the highest gear, rather than something having to do with engine management.

 

Nope, manual here. Valve timing changes the sound significantly, especially with the straight pipe.

 

Remus is a good option also, i like the finish and CF tips of them and the akrapovic.

 

What is the cost of the IPE with valve for F56 JCW ?

 

Its all right here, Valvetronic is the valved system : https://www.ecstuning.com/Mini-2015-...t/Performance/
