Hello everyone, many years ago on my ST Mk7 I installed the Cobb RMM, the old version with the holes. It got damaged and I need to replace it, but I’ve seen that it was updated with the new version without holes due to “resonance issues.”

How does the yellow+purple Powerflex RMM compare to the old COBB one I currently have and to the new version? No track days, just spirited street driving.

Thanks!
