just to point out there are no TRUE hi flow cats, some cheapo companies half the amount of lining, Random tech ( not our random ) uses the correct amount of lining but makes the cat diameter larger and more spacing to let air flow better. when getting a after market cat look into the pipes and make sure you can shine a flash light thru it , that it's got no trace of carbon in it and that you can not see thru it with out a flash lingt, check to see the neck size is the actuall pipe size you need ( not a 2" pipe with 2.5" adaptor )
