Hi all, Has anyone seen this mild to wild exhaust for an ls3 engine ? If so what web site has it to look at. I have seen something like on you tube but can not find it on the web . I did see nika some where but can not find it , Thanks, Pete

 

As fas as I know its only for Vettes as their mufflers come with valves that open/close automatically. All it does is let you open/close the valve.

Its pretty much an electric cutout
