I have a pretty stock 2004 GTP and just bought a SS catless dp with sims and am planning on getting Wizaired CAI, 180 tstat, and Autolite 104's and am planning on getting a zzp MPS. What size pulley should i run for my specific setup? and is there anything else anybody would suggest for this setup? also i have zzp shortened dogbones, just for future reference what headers would i be able to use without hitting my fans?
