I have a 2000 v6 manual, 4.10 possi, and it had 95,000 miles on it. Which one of these products would help me get down the track the fastest? Underdrive pulley, cold air intake, headers back exaust(not including headers) new plugs and wires, or something else that would be around 300 dollars?

 

Their all gonna be the same: .01 second gain maybe...

I would say do exhaust.

 

i'd personally go with a Used tuner for around 200. (i picked up my diablosport for 185 shipped) and than a drop in K&N... than you have a couple bucks left over for whatever else you want

 

Keep saving. Nothing for $300 is gonna make you much faster.

 

+1 on the used tuner/ CAI idea
