tti or Hooker Super Comp headers into a 3 inch exhaust pipe size. Based on actuall output, *I Think* the Hookers should be better for a track only car being launched like a golf ball and turning hi RPM's.
Hooker Super comps stomp a mudhole in tti step headers. We had a pretty stout 394 on a dyno and the super comps were 27 hp better than the tti's. No other changes except the header swap.
