Has anybody got OBX longtubes on there truck. If so, do you like them and how much of a pain in the *** were they to put on. I've always done my on work, but this is my first modular engine. I feel like I'm learning all over again. Oh, by the way, the truck is a 99 f-150 4x4 5.4 auto. Thanks

 

i have them on my 2002 5.4. and well, it was more of a PITA to take the old stuff off than put the obx's on. they fit nice and can hook up to your factory exhaust with the y pipe they have with them. i have high flow cats on mine instead of the resonators, and let me tell you they sound MEAN! and a hint for doing them yourself.... SOAK YOUR BOLTS WITH PENETRATING OIL! well before you start doing them! oh ya, and have some beer and it wont be bad at all. well worth it to me!

Thanks, thats what I wanted to hear.

 

yeah, removal wasnt pretty on my 4.6 manifolds. install was a breeze! just dont tighten your bolts too much when your putting them in so you dont have to fight them all in. just a couple threads each until you've started them all
