I have an evolution racewerks in my G30 (B48) and it's fine

If you're running a 200 cell for emissions reasons I think that's probably the most aggressive you can go. If you live in a jurisdiction which doesn't have emissions tests just go straight for the catless.

If you have a opf/ppf/gpf you should do a midpipe with the particulate filter delete at the same time you do your downpipe & get a tune all together.

If you HAVE TO get them piecemeal, get the tune first and then get the midpipe and then the downpipe last. I have heard some people who only did their downpipe suffer from issues relating to the gpf/OPF still being there.

Honestly I don't think the brand matters much. Don't get too obsessed about the dyno readings the manufacturers give you. It's so easy to fudge numbers on these that it's impossible to compare between brands.

Use common sense when it comes to exhausts... it's not rocket science, diameter of the pipe, aggressiveness and quality of the bends in the tubing, quality of the welds. There's not much secret sauce here.
