long tubes

  1. BBK Long Tubes w/ Catted midpipes

    5.7L Exhaust
    Just bought a set of BBK long tubes with the catted mid pipes and was wondering if the mid pipes are made to attach to the stock exhaust or if an aftermarket cat back is necessary to install? I have a resonator delete with stock mufflers on ‘13 rt classic
  2. Long tube headers W/ Off Road midpipe

    5.7L Exhaust
    I just purchased Long tube headers from JBA and their connecting mid pipe. I am currently tuned and have a tune ready for after the installation that will also tune out the CEL from the O2’s. Do i need extensions for the o2’s and if so how many do i need? If i’m tuned, can i just plug the O2...
  3. Kooks Long Tube Headers And Cats? Tune?

    Challenger Performance Mods - Engine - 5.7L HEMI
    I plan on deleting my cats, as well as some Kooks Long Tube Headers, And a tune. I’m wondering, if I just put headers and cat delete on, do I have to tune it before I start it? Can I drive it home from shop? 2017 Challenger R/T (5.7, 8speed)
