Exhaust Valves Closed in Sport Plus To Pass Sound DB
So I'm planning to go to Laguna Seca in December. I currently have AA midpipes and I dont believe it will pass sound with the valves open. Is it okay if I unplug the exahust valves when they're closed and then put it into Sport Plus? Would this affect anything? I'm just thinking it should be okay technically since it's just closing the valves completely.
