keSSel_runner Posted February 22, 2013 Report Share Posted February 22, 2013 Just bought the magnaflow 3" spun cats part #59959, but just realized they are labeled as pre obd2, so will these work on my 03sss? Planning on putting them on with the coated pacesetter longtubes then a tune. Quote Link to comment Share on other sites More sharing options...
06 v-maxx Posted February 22, 2013 Report Share Posted February 22, 2013 I dont see why they wouldnt work, But maby they would throw a cat low efficency codes which cold easily be turned off in the tune. My dynatech cats would throw codes until I turned the code off. Quote Link to comment Share on other sites More sharing options...
chpspecial Posted February 22, 2013 Report Share Posted February 22, 2013 These cats won't pass CA emissions on a abd2 equipped vehicle or any other state that uses CA smog rules. So they aren't legal OEM cat replacements for an 03sss Quote Link to comment Share on other sites More sharing options...
