hey guyz, next month i'm getting some SLP headers and Underdrive pullies for my iroc, also when i put this stuff on i'm gonna rip out the A/C and Smog pump stuff, should i not get the pullies since i'm gonna be ripping out the 2 other pullies? will this hurt me or help me buying these pullies? well thanx in advance for ur help.. mike

 

I liked the underdrive pullies, they helped my car. I also removed the smog pump, but not the A.C. When you get the pullies, the 2 piece set gives you more underdrive, than the three piece set. I found this out the hard way and now I have an extra aluminum water pump pulley, that cost me like $80.
