just curious if anyone knows...cause i have looked and cant find...do they make an offroad h-pipe or an offroad x-pipe for an 06 f150 with 5.4 and 4x4 if that matters..i was wanting to cut the cats off..and my lil bro has an 05 and getting a bad rattle from his so he was wanting to do the same..thanks

 

I think the only thing out there is Pacemakers off road y-pipe that matches their long tube headers.

 

was trying to get away from putting headers on for now..but possibly look into doing them later...would you be able to cut the cats off and just run straight pipes to the mufflers?? i know on my mustang that i had i had to put o2 sensors eliminators...i also had a programmer that i could turn them off with..do they have such a programmer for our trucks?
