I’d keep the bit about modified structural brace bit shtumm, not really kosher to remove or modify that. Is critical, does affect your insurance.
Apart from that it doesn’t look like a standard exhaust, first reason for Mr Plod to pull you over and pull out his iPad and just do a quick roadside check on noise compliance.
For what it’s worth the stock bimodal program does open when you don’t want it to sometimes, like when Plod has microphone 1 metre away from rear and you need to make it as quiet as a dishwasher.
Reason I mention it was pulled up in Brisbane on the Hornibrook and given a full once-over, reason being suspected was over limit due to aftermarket exhaust.
