i recently got my motor together and dynoed it with 1 7/8 headers on the dyno. It put out 460 horse. I want to put true duals on the car and have heard that the hedmans are the easiest to do it with. Will the 1 5/8 primaries hurt my performance that bad and what size piping should i use for the exhaust.

 

i would say with that much power u would be better off with the hooker 1 3/4 headers. also use 3" pipe for the duals.

 

didnt hooker used to make a set of 1 7/8 longtubes for thirdgen's with small blocks, i know they got them for the big block swap
should i come off the collectors with the hedman x-tension the into an x-pipe then to bullets then dumps? or does anybody else have any ideas, the car has an eibach pro-kit but soon to be moroso trick springs up front with v6 springs in back.
