My ex ran them on his Mustang GT and they were great, i would imagine it would be the same on the F150.
Here are the Design Notes: 2,3,9,13,16 2: Slip-Fit Collector So i'll have to mod the pipe to fit to the Slip-Fit collector since we have Flanged collectors. 3: Hook-ups for smog & engine management sensors where required Prolly will need a 6-12" o2 extention 9: Catalytic converter must be relocated Might as well get my inspection done and then just remove my cat's completely, other wise the driver cat is going to have to be mounted further back than it is intended to be, coming pretty close to my gas tank. or just move both cats to the factory exhaust space since i have that huge CANON of a oem muffler removed. Thoughts? 13: Long Tube Header 16: Y-Pipe available to connect to stock system
look at the bottom header. do you see that small tube that stems off near the flange? whats that for? is that the upstream o2 or what?
right, the oem system is like that. but... if i put these LT in, then my upstream and downstream o2 are both before my cat then, and i would have to put a plug in my cat (if i even kept it). so thats why I was asking if that lil stem plug near the flange was an upstream o2 spot. if all that is true, then I think I am gonna get my inspection done THEN do this swap. maybe...
