  Wow!

  An awesome addition to my 3.8L Wrangler! I was surprised at how much gain this provides.

  They fit like a glove.

  Header welds are high quality, ports are matched and they fit like a glove. RIPP directions are well written. You will need a set of manifold gaskets if you had an exhaust leak like I did, gaskets are cheap. Kit comes with all mounting bolts, including metric bolts for cylinder head. Use your factor heat shields to prevent heat damage. Do not run without them. Factory heat shields fit over headers without cutting. I’ve put over 2800 miles on the new headers without any check engine lights, melted wires, heat damage, leaks, or problems. Under hood heat levels are lower than before with OEM manifolds and catalysts in engine bay. Water crossings did not damage them. Keep your OEM muffler if you are not going to run a resonator. It will keep noise levels down under 3200RPM. Above that it talks. If you have an aftermarket muffler install a resonator, glass pack or Hush Power Resonator under the driver’s seat. Without one it will be loud. On the driver’s side run your oxygen sensor extension around the outer edge of the fire wall heat shield. Drill small holes around edge to secure zip ties. Use the factor heat shield bolt to secure the oxygen sensor wire to on the passenger side with a zip tie to keep it away from hot parts. I made a bracket out of an inch long piece of angle iron to zip tie the oxygen sensor plug to. On the driver’s side post catalyst oxygen sensor use six inches of heat wrap around the oxygen sensor wire to protect it. Give you self 3 to 4 hours to install them in a garage if you are handy and budget time for broken bolts. Header cylinder head bolt torque is 200 inch pounds, anymore and the bolts will break during engine heat cycles. When installing jack up vehicle by frame and let front axle drop. It will make installing driver side header easier. It goes in without removing any thing, just work it in. Use your factor heat shields to prevent heat damage. Do not run without them.
