If you have a 3.9L, don't do true dual, cat back is best (true dual you'll
lose too much low end.
treat your truck as a system. You won't get as much performance from an
exhaust mod if your intake is still chokin the truck.
my .02.....do the K&N 1st...it's cheap and the results are noticable...then
just work your way out
exhaust
chip etc
I'm assuming that you've already changed to performance wires and plugs
