2nd2none Posted August 17, 2011 Report Share Posted August 17, 2011 So I've decided i'm going to pick up a set of the Dynatech longtube headers and was trying to decide if i should get the X pipe with high flow cats or just ditch them and go with the offroad X pipe. I'm in Cali and I know the headers themselves are not smog legal here so is there any reason I should even bother with the cats? If I find a smog tech that doesn't notice my mods would the high flow cats reduce emissions enough that it would still pass the sniffer test?

03 DSG Snake Posted August 17, 2011 Report Share Posted August 17, 2011 If you ever get pulled over and they see no cats you will get royally screwed. I would run them. My 03 passes the sniffer with headers and cats. I plan to setup the Shelby like that as well. Link to comment Share on other sites More sharing options...
07SGT4578 Posted August 17, 2011 Report Share Posted August 17, 2011 I would go cats in your situation since you live in Cali. If they catch you with no cats, they can seize your car. They will notice you for sure either way, better safe than sorry. Link to comment Share on other sites More sharing options...
