custom make exhaust bypass valve?

There seems to be very mechanical people on this forum, so i would like to ask if anyone has done this.

Is there and can you get a generic vacum/electric bypass valve and splice it inline with the pipes before the muffler?

It may not give any HP increases, but I am sure there is a way that a pressure switch can be rigged to open under open thottle and give a more agressive note to the car.

Just a thought.
