hey guys i know this has probably been discussed lots but i need some quick info. im looking for a set of headers for my truck (2000 f150 4x4 5.4L) and read that shorties don't do much in hp gains and torque, so considering long tube which will eliminate all my cats (back 2 are already gone) and have true duals. with long tubes will they have holes for the sensors? im not planning on running any cats just some sorta of glasspacks/mufflers (ideas?) Any engine troubles with long tubes? Last but not least is anyone running pacesetter long tubes to get some feedback on?

let me know
thx

not me i have the pacesetter shorties with no cats and true duals..but for your question. no they will not have O2 bungs you will have to get aftermarket flanges with them and then get O2 sensor extensions..i'd definantly get a custom tune though

FactoryMod

rampage....with the shorties did u feel and power improvements? and what did you did with all 4 of your sensors?

rampage12

i could tell the difference ..if would of had an extra 300 or so id went with long, i hooked the front 2 back up and removed back 2 via programming, if you go with long you will have to get o2 extenders to hook front one back up

FactoryMod

ok cool, i wonder by taping into the pipe and putting the back 2 also in could work? what kind of mufflers are you running and any sound clips?

rampage12

if you are removing all cats then it wont matter if you reinstall rear o2s, there gonna throw codes like crazy, running hpipe and dual 2 chamber thrush welded mufflers..i 'll get sound clip up tomorrow was planning on posting it on you tube to add on here
