So basically somebody stole my catalytic converter, but it is what it is. and that got me thinking to put on a new exhaust on since they cut a chunk from the manifolds. in the perfect world, I'd like to put on some BBK long tube manifolds, and the only manifolds they make for an automatic Mustang are for the Foxbody generation. In order to make them fit I would have to remove the EGR, so if I'm doing that ill pull the smog pump out too. but the problem I have is that since there is no cat and no EGR it will throw a CEL. I was thinking of also putting a Megasquirt Gen 2 into it, but since the Clean Air Act, the aftermarket ECUs won't limit the emissions. Is there a way around deleting the Cat, Smog pump, and EGR without throwing codes or messing up the ECU. or can I send the ECU somewhere to be able to disable the emissions from the ECU itself?
