Keep the N55 + Akra Slip On combo, but add the wireless remote
so that you can toggle between code white (Closed Mode) and code red (Thunder Mode) !
Trust me, with the valve closed, the system is muffled that much, that you might think that you got back the stock 1M exhaust + stock N54. Arriving at night without awakening/harassing the neighbors is possible - it only requires the touch of a button.
