loud pipes/soft pipes with the switch of a button!

Is it possible? Has anyone ever seen or heard of such a thing? To have an extra set of pipes and a valve to direct the exhaust through a quiet set and a loud set. I'm very curious and was thinking about looking into what would be involved.

I know I have seen (probably in summit racing catalogs) a valve that switches car exhaust between stock exhaust and open headers. I am sure that something like that could be done BUT jetting would be an issue. I would say although YES at the pipe end it could be done switching between open drag pipes and baffled pipes. But you would either have 1 way running great and the other poorly or have to jet somewhere inbetween and never have perfect running in either position.....but hmmmm could something like that be done with EFI??????

yes, it could be done with an open loop efi system. the open loop will allow they efi system to adjust on several variables, vs a closed loop system is preset for certain rpms much like a carberator

You stole my idea except I was going to do it to my suburban. I've always wanted that big truck sound, but it's a suburban. I thought it would be cool to have both types mounted and then crawl underneath and change the flow direction. I never got around to researching the fittings that would be needed. Sorry this was a little off topic.
