Unhappy Strait M Performance exhaust rattles between 1.7 - 2.0 RPM

Hello there,

I have recently evolved my exhaust to Catless Downpipes, and strait M performance silencer, omitting other catalytic converters too. At the moment, I can hear embarrassing rattle when I accelerate on the second and above gears between 1.7 and 2.0 RPM. Rattle appears only on a slight load. If you drive on a higher RPM, no rattle appears. If you start to accelerate from the first gear really hard, no rattle also.

Have any one experienced this issue?
It sounds exactly as this M5 sounds, but it starts at 1.7 and disappears on 2.0

Solution for this M5 is not quite working for me. Their downpipes looks differently.

My car is 12 000 miles.
