clearing the self learn would probably be a good idea so that the ecu learns the new airflow and exhaust patterns. altough this will not avoid the check engine light on when the ecu detect the cats are not cleaning up enough lol.

 

He shouldn't and probably doesn't get a CEL with HFC. Test pipes do this, NOT HFC.

It woudn't really matter if you reset your ECU. It won't hurt anything, but I doubt it will help.

 

fast intentions HFC gave my bud cat effiency codes within a month or so. so have magnaflow HFC on various other ppl. depends on manufacturers i would not say it WILL happen but its always a possibilty . but ditto on the effects being postive most likely no
