Pacesetter Longtubes?
i bought the black pacesetter long tubes about 2 months ago, and ran full 3" exhaust w/o cats into 3"dynamax bullets dumped in front of the rear tires.. i didnt have any problems with these headers, they fit great...the only thing is you might want to get better gaskets (copper ones) instead of the Felpro ones that get sent with the headers.. best headers for the money..gained over 30whp/30tq
oh yea, you will probably need some 02 extenders because the factory ones wont reach i went here for them and they are perfect length..www.ninosport.com. they are for the ford mustang but work with the ford f150
im getting long tubes. soon for my 97 4.6L will i need the o2 extenders?? are those for the front or rear o2's? and will i see about the same gains 30HP? it'll be headers no cats and dynomax superturbos. im going to the dyno soon for a before and after dyno. just wondering thanks alot!...do you live in michigan i see a boss 5.4 F150 like yours driving aroudn all the time.

i had to get the 02 extenders for the front two that are on the end of the headers, the other two sensors you wont need extenders because you get to put the sensors anywhere in the exhaust, so just put it close to the plug in..No i'm from Illinois about 2.5hrs from Built54.. your hp might be different on whether or not you have other supporting mods and the size of your exhaust pipe. i also dont run 02 eliminators, all 4 are still pluged in while the rear 2 are turned off by my Predator programmer
i have a K&N 77 CAI. and E-fans i have pacesetter shortys right now and dynomax superturbos no cats. So i have to have those extenders? im going to buy the front 2 o2 senors before i put the headers on. i mine as well those have been on there for 133,000 miles without being chaged so ill just grab a pair and put them in my headers before i put them on. it will be 3" pipe after the headers. these are the headers im putting on soon http://www.autopartswarehouse.com/de...P40702227.html Are these the extenders your talking about? http://www.ninosport.com/BBK-Oxygen-...=2&category=86
