helped a friend install a ZZP 4to1 header and 3" downpipe lastnight, 1.5" primarys(sp) on the header. Amazing quality, nice welds and the ceramic coating on the inside and outside of the header is awsome. The difference it made was phenominal also.Before it sounded stock unless you got on it and now its mean even at idle. should be in the 260-270whp range seeing is how hes got the stage 2 pulley and injectors aswell as the airbox mod.oh and LSD :p
