i have flowmaster exhaust and cold air intake, what kind of pulleys should i put in to get the most horsepower out of, and about how much would it cost?

 

$200 bucks will get you a great set of UDP's. Steeda UDP's are good, also you can order March UDP's, make sure you refer to my thread in the 4.6 section and get the correct part numbers so you don't end up with a piggy back setup like I did.

Make sure you get pulleys that come with a crank/puller dampner as one solid piece. Piggyback UDP's weigh alittle more and do not allow you to use a timing adjuster.
