I got this crazy idea today. Take a glass-pack muffler and slide it onto the exhaust pipe all the way so there is no muffler touching the exhaust gases. It would give you the performance and sound of a straight pipe with the appearance of a muffled system.
To do this, just get a muffler that has its smallest diameter able to slide over the pipe. Then have pipe couplings to make it seem like you thought a larger muffler would increase flow. Then at the end, have a tip on the muffler. Then if need be, just slide the muffler back some for a muffled system.
The only downfall to this would be if you got a sound check done if you got pulled over. For inspection/emission, just slide it back.
