Alright so I'm about to have so major mods done to my car, Atleast major compared to what I've done so far. Someone told me that I should go with headers with these mods but I don't know for sure.
Car Info
2002 grand prix gt
67600 miles
Current Mods
k&n drop in filter
NGK Iridium plugs
ZZP 2.5'' bolt in downpipe with high flow Cat
Poly Motor mounts (not really engine realated)
Strut tower brace (also not related)
Parts ready to go on
GT1 camshaft from Comp cams
Hv3 High velocity intake insert
180 thermostat
Parts that I have for cam install
Timing chain dampener
12 COMP CAMS reuseable rocker bolts
GM oem aluminum intake gasket set
front cover gasket
ARP assembly lube
valve cover gaskets
crank bolt
cam bolt
Factory replacement timing chain
new intake gasket (for the Hv3)
So my question, Is my downpipe enough for the cam untill I get power logs or headers? and are power logs better for my car than headers? Because Ive heard on N/A cars headers result in a loss in low end torque and thats kind of the only thing these cars got going for them plus im not going to be driving over 100 I dont need high end power I need the low end stuff for rocketing in between lights.
Also any input on perfourming this install and things I might still need to do so. Was thinking of possibly going to PRJ but maybe ill do it myself, or maybe Ill keep buying parts and just do a complete rebuild in the summer.
