Emissions legal headers

I have to stay emissions legal and I have heard that it is a real pain to run a cat with longtube headers. Are mid-length headers any good? Would they allow me to run a cat??

Re: Emissions legal headers

SLP and JBA sell emission legal headers that still allow you to mount cat(s) in the stock locations.

Re: Emissions legal headers

if its got cats on it and all the egr and air hook ups your emmissions station might pass you but according to federal law the the number and location of cats must be kept stock.

Re: Emissions legal headers

How much of a pain would it be to attach a cat to the Jet Hot y-pipe??
