I have a 1998 pontiac gt with a 2002 gtp engine. I wanted to know what kind of headers I should get. I have a 304 stainless 3" catted, a w-body cold air induction system, and a qwikchange pulley system. I was debating between pacemaker headers($350) and stainless headers($700) from zzp. and what would the safest pulley be for me to use? It still has the 3.8 on it but i have a 3.4 pulley i could use
