Anyone cut open a Stock Muffler?

Post by xcidmigs »

I just heard/saw my co workers 16 SS sedan which has the bi modal exhaust valves in the mufflers. Its very impressive and I would say a great piece on a DD car. I'm assuming buying the GM parts new is $$$ however I am wondering if anyone has cut open the factory PPV muffler to see if there would be any way they could simply have an extra "outlet" cut into them with perhaps something like a plate for a generic exhaust cut out valve to be welded onto. I realize there would be other ways to do that like just cutting into the stock exhaust piping somewhere ahead of the mufflers I'm just curious as I don't see any cut open PPV pics anywhere on here and clearly many people have removed theirs.

It sounds like just buying a set of electronic exhaust cutouts would be a much cheaper and easier alternative.
