exhaust control valve

I just did a GSR swap in my civic, i have a greddy header, greddy catback exhaust and i punched my cat so its basically just pipe and it looks like i have a cat, the cops in my city are crackin down on loud exhausts, and i was wondering if anyone had tried the new arospeed exhaust control valve. I could just close it down some when i was near cops. let me know, thanks

the Arospeed ECV is a neat toy. the Ferrari 550 Maranello has it on 1 pipe of it's dual exhaust; a buddy pointed it out - others knew it & also pointed out that the Mitsubishi 3000GT VR-4 has it, too...like i said, neat toy.

ok so its a neat toy, but does it reduce the sound coming out my exhaust when i close it? Thats why i want it i want to make sure its worth the 130$
