I did turn off the pops via bm3 though as sometimes they were to much - still has burbles though.

Do replace the lower cat bracket and the turbo seal - I didn't the first time and had to do the job again to get rid of leaks.
Good call. I replaced the seal, but not the copper gasket to the cat back, or the brackets/clamps. I also did not replace the bolts on the stiffening plate. In hindsight, I would have replaced it all in order to prevent future issues. For example, the downpipe to turbo clamp/bracket got a little mangled.
The cat back seal and bracket are one piece. No need to replace the top bracket imo.
