Butterfly Exhaust Valves

[XY GTHO Ph III]

Does anyone have Exhaust Butterfly Valves on there Cobra. I ask as I want to drive my Cobra to work but I leave around 5:30am so with the Cobra being so loud I will become know to my neighbours as that prick that starts his car at 5:30am in the morning guy. I saw a product that Harley's have on there bikes where a butterfly valve is placed in the exhaust and when closed 90% off it quietens the exhaust sound dramatically and when you get out on the freeway you can open it up 100% and you have the sound and performance like it was not there. Anyway I want to put those on my Cobra to lessen the noise when I start up and get around the neighbourhood, Thanks

You may want to look into silent choice (we use it on the boat) but it reroutes thru mufflers..
