Catless setup with top gear exhaust

[M5 QC]

I install downpipes catless with intake and stage 2 tune on oem exhaust last year and really love the sound. we can hear the PRAAACK! When realease the throttle. Now i have install top gear exhaust and fuck dont love the song! You can hear a little bit more spool from turbo in exhaust but no PRAAAACK and i think my car is more quiet than before with oem exhaust and catless downpipes.

Is it good for our car to run catless with oem exhaust and stage 2?
You guys with catless setup and aftermarket exhaust have a praaaack?

Oh and i forget i have to cut the bracket because the the mid pipe section to front pipe dont fit....poor fabrication and buy better clamp because too cheap and less leaks
