I found the headers I want from ARH!! Very nice long tube headers for my 4wd. They offer them with cats or without cats. What do you guys think are there cats a must or can I use my factory ones?

Allgonoshow Thanks for the pics! Those look really nice! Looks like all the factory o2 sensors bolt right in. Do you have any problems with the check engine light coming on with the new cats?

you will get codes 1120/30 and 1131/33 if i remember correctly, both can be turned off with tuning software with no issues
if you have a catback and add headers it's loud, for me, anyway

Very good to know! Thank you very much I am going to call Nick and get them ordered. I am running a Flowmaster cat back with a Super 40 Series and a single tip running like in the stock location.
