If the ranking is not necessarily based on the "bang for buck" criteria, then let me and another suggestion:

supercharger!!!

 

Yes.....I was thinking low budget stuff, but I agree if $$ are there then juice it up with a Twin Screw!!

 

Bump...........Let's here em!

 

1.Cold Air Intake
2.SCT-X2 Tuner
3.Gears 3.73 for the auto's, and 4.10's for the manuals, that is if the v6'ers are using the same trannys. I am not sure what tranny they use.
4.Underdrive Pullies
5.Nitrous Kit

This is probably what I would do if I had a V-6, at least while keeping it cheaper,
then I would probably add a supercharger. Which also leaves it at 5 because you would have to delete the underdrive pullies with the s.c.

But alas you would want a good tuner as well so thats actually six,LOL

 

Yes... Definitely a CAI and Tune will help you go faster. Exhaust will make you sound faster. Stripes will make you look faster

 

A muffler is the Biggest Bang For The Buck! Btmo!

What about headers?? Do they add enough "Bang for the Buck"??
