Is there a way to have 4 sets of pipes for a v8, 2 for each side, one with a muffler and one without?

I've thought about a "Y" after the header, and capping the un muffled pipe with a removable cap of some sort. Would that work? Or would that just make a mess of pipes and increase problems with back pressure?

I'm thinking a muffled pipe for street driving, and an un muffled pipe for shows, races, or whenever I wanna be loud.

And has anyone ever ran straight pipe with a "X-pipe" somewhere in there? How would that sound as opposed to just a straight pipe? i kinda want the old raspy muscle car sound.
