What about Heat dissipation from the engine bay ?
Anyone have data showing lower underhood temps post headers on a supercharged setup ?

As King said, front cats are most restricted. If you can score some cheap new era cat deletes, do it. I'm going with 2" SE catless headers. I have seen the dynos and ET gains, and the long tube headers pick up power and torque everywhere on the powerband, n/a or blower. But the gains seem to be more noticeable on blower setups.
