ok whoever has the speed daddy headers on their l36/l26 engines let me know how you feel about them, or if anyone has data to back up that they help, cause im debating on getting them.

ZZP says that they are very overkill for my setup and N/A engines.

This is my setup currently

2006 3.8 SERIES 3 L26
HV3 insert
Northstar 77mm Throttle Body
CAI
ubend/cat/resonator delete
ZZP PCM
TB spacer
Underdrive waterpump pulley
Overdrive alternator pulley
