How loud would it be/could I pull it off without looking totally redneck?

My flex pipe is gone, and the rear half of my exhaust is all kinds of clamped together and rusted.

I'm really tempted to put a chrome stack through the hood, or possibly relocate the battery and send it through a small muffler and then out the fender wall(and up a chrome stack)


How deafening would that be?
