98 Trans Am LS1 true dual exhaust upgrade available?
 

Now that my 69 Firebird 400 is finished (yay!), I'm turning my attention to our 1998 Trans Am convertible with the LS1, non WS6, exhaust.

Currently it has the single pipe back from the LS1, the stock setup.

Is there a true dual exhaust upgrade available? I thought Pypes might have it but it's not on their website.

Any ideas or suggestions are welcome, thanks in advance.
