The catless DP will definitely make it sound louder. You'll hear the turbo whistle more too.

You'll need a tune to remove the cell light that will be triggered by having no cat.

Another consideration is depending on which market you're in - you may have the dreaded OPF filter. By removing the cat, you're likely to destroy the OPF filter which is positioned just after the DP
