Yesterday we tried out my resonator delete with its pipercross filter.
The first 5 km a bit jerky when starting. After 20 KM the full throttle for the first time and because of that also very jerky when accelerating.
After 40 KM absolutely no problems and great draft. Diverter valve is now a little better to hear, he says, I can also confirm. Clearly not as great a suction sound as with the MST intake but at least.
He is absolutely thrilled and now wants to delete a resonator (again) : S
If someone really has problems with it and wants to get rid of it (in the color black , no matter which brand), please contact me.
