with my jardine catback if i added dt shorty headers would i have to get rid of all my cats?? i really want to add DT short headers but not if i got to gut my cats.

From my understanding the DT header eliminated the pre-cat on the stock manifold. You'll still have your main cat under the truck though.

okay great. so that means i would still pass emisions right?

buyobuyo · 08-25-2008, 06:09 PM

should be able to unless they throw a fit about the pre-cat being gone.
