	| Has anyone had experience with those butterfly devices you put in the exhaust? They can be opened and closed by a solenoid i think. The butterfly plate that closes has lots of holes in it, so it still gives a restricted flow. 
 Anyhow.. thought maybe it would be good as on the freeway and when cruising have it closed and hopefully quieten things down. Then when u want a fang open it.
 
 Any first hand experience with these?
