Just pick the catback based on sound preferences alone, they all give about the same power.

Replace the main cat with a new higher flowing cat, like Car-Sound.

If you dont have a visual emissions check, then go with TPiS or Hooker Headers.

I tried to get a baseline run on my 86' before I did the header install, but some high HP **** busted the dyno a couple of cars before it was my turn.

Here is a shot of the run after I installed TPIS headers, and a Random Tech high flow cat. The mufflers are LT-1 style, and very quiet. I do not know if they are stock, but they do not seem to have any obvious aftermarket labeling on them.
