Seems Holley discontinued their tube headers for the Gen3 Hemi and their engine mount system. Something about EPA restrictions and moving the O2 sensor from its stock position. Now they offer basically a log manifold. That has to kill power. Anyone know if there are other header manufacturers that might fill the gap? TTI still has headers, but you have to use their mounts. The TTI mounts don't work well with an 8HP auto trans and very minimal tunnel mods.
