I have a couple of questions for you all. What is a underdrive pully and what would a high performace one do for my truck? Also what tpe of exhaust do you all recomend; I was wondering because I thought that a catback is a single pipe that splits into two or do you all recomend duel exhaust? (I live in VIrginia curious about the laws), and what type or brand of headers as well. Have herd about Borla headers and if they make them for my truck and where to find them? What chips do you all recomend and where to find them? Last but not least what fuel filters do you all recomend.

Thanks for you all's help.

Welcome to Ford Truck Enthusiasts!

The people who sell underdrive pulleys have to say this:

"An underdrive pully is a smaller crankshaft pully (the one that does the driving) ...by reducing the size of the pully it gives the engine more leverage over the drag of the accessories. The power saved from the accessories is therefore available to propel the vehicle better. "

Other people point out a few of the drawbacks, such as this:

"May have charging issues at idle under a HEAVY load....Will need a shorter belt with pulley. "


Gibson & Flowmaster Exhaust systems are the most popular for the 3.0L Ranger.
