You can install catless downpipes with your current mods without any issues.
You will get an engine check light, but that can be suppressed by the JB4 or the BMS can flap module ( or you can just ignore it)
No need to worry about your turbos, catless downpipe will help your turbos by removing the pressure caused by your cats.
I do strongly recommend that you get a JB4 as well to take full advantage of the performance gains of going catless.
