Even at only 600km, I have noticed that the sound is changing, deeper and louder, definitely more is better!

Finally got around to installing my cargraphic race muffler to pair it with opf delete ,it is loud but not obnoxiously loud ,with an exotic soundtrack. There are zero drones with the flaps closed ( almost oem quiet with valve closed ) ,and a angry scream when flaps open. I’ve also notice a significant improvement top end power ,a bigger rush at over 5k rpm ,I can definitely feel the power gain which indicate to me that the stock exhaust system is really restricted. A full exhaust is a must on these cars in my opinion ,totally transformed the car.

I think you just have to call them? I bought a Capristo system from them for my F80 M3 a few years ago, and only way I could see they had it or price was by calling. Best price for that exhaust I could find after reaching out to many other vendors.

I'm curious to see what's the effect of just deleting the OPF and keeping the stock muffler

i was running the opf delete with stock muffler ,before the cargraphic race muffler arrived. I suspect most will be happy with an opf delete and a valve controller.
