performance upgrades for a 2006 t/c

[beanride]

I am looking for performance upgrades (supercharger, brakes, suspension, etc.) for the 2006 Towm Car. The car is fully armored and very heavy. Any help would be greatly appreciated.

There isn't anything really out now. You can check to see If K@N makes a drop in air filter for it. Best thing is to go to a muffler shop and have them put bigger piping from the cat to high flow mufflers out the back.
