Curious as to if Mac midlength headers will cause my car to fail emissions or not. I'm in Connecticut, have a Borla catback if it matters, and won't screw with the cats.

Don't want to bother with trying to find legal longtubes for a mostly stock motor anyway, so are the mids ok, or am I going to be stuck with shorties?

 

Not sure about CT, but here in CA you cannot move the location of the cats. Thus LT's and mid-lenghts are illegal and shorties are the only option. I would not get shorties if that turns out to be your only option. They don't offer good bang for the buck, plus you should get more engine mods first
