headers are definetly worth it, only person i know on this forum with headers is xS3X check for his posts. i dont think it will make any differnce if you got headers from supersprint, Racing dynamics or Rennsport, they should perform roughly the same(just my opinion dont quote me on it). there was a dyno result with xS3x after he installed the headers. at the time of the dyno he had (gruppem intake, headers, software and an exhaust) his car managed 262hp at the crank. do a search you will find it.
