Dual exhaust over-usage

It's a way for more $$$ out of you when you need to replace them. I had a Lincoln with duals, but like most said it was a single pipe back to 2 mufflers and tailpipes the dealer said that was to make it quieter, when it was time to replace I went with a single muffler and tail pipe. it does give some cars a more balanced look from in back, they should have chargers and Challengers with the 6's full duals IMO. they did that with the new Mustangs 6's my neighbor has one.
