anyone have a 2001 F250 4 door 5.4 4x4 ? want to go to duals and do it myself, any good kits??? muffler shop wasnt much help, wanted me to get collectors for the o2 sensors!!! a link to a good source would be great, havent found much for the 5.4...just diesels

 

check out magnaflow
pretty easy to navigate site
find the part number then enter # in search engine...lots of replys to go through but worth the price

Also might try diesel speed shop, the way the economy is they will probably be willing to make a gasoline sale LOL

 

well i tried them all, still no duals for my set-up!!! WTF??? ive seen them on trucks just like mine but no one sells them!!! only place i found would do it wants me to get the parts!! hell if i find the dam parts i'll do it myself!!! ARRGGG!!
