Stillen headers?
Have burks HFC and just got headers from stillen, probably going to return them after seeing fast intentions long tube headers, but have a thought....with nismos tune and the fact that i will definitely install the stillen supercharger once released, should i just keep them? I know the 370z without a tune is showing minimal hp gain/torque gain, but it seems that it might show greater gains and benefit with the tune and increased airflow from a supercharger, while still keeping the HFC (I live in cali, and don't want to get towed for no cats)
