just put mine on the other day, waiting to figure out what to do with the resonator with no bosses/bungs for o2's other than that, i like em.

 

You getting codes then without the O2 in there? Where did you get your leaf springs too I need some!

 

trucks not running yet, still finishing things up with the 4.6 to 5.4L lightning swap. i went and got some boss' to weld onto my resonator since these guys obviously sent this resonator out without checking it.

i went to alcan spring, www.alcanspring.com
they'll build anything ya want. i must admit, for being higher payload springs and high arc, they sure do well all around. i could have gone for more articulation tho
