This kit allows for the removal of the Exhaust Gas Recirculation (EGR) coolers from your truck (if you wish to remove the EGR valve and restrictive elbow also look here). Kit utilizes the existing EGR exhaust port to incorporate an external wastegate to allow control of high exhaust backpressure. The 6.4L engine was designed to use EGR as a wastegate of sorts and has 25% EGR flow at max power. For peak performance EGR is not desired and with many tuning programs the EGR is turned off. With the EGR turned off the exhaust backpressure jumps to overly high levels resulting in lost power and un-needed stress on engine components. This kit is recommended for all power levels but becomes a necessity when power gains exceed 300hp. Kit includes all necessary components to eliminate EGR coolers from vehicle. The base kit requires you to weld in the wastegate pipe to your existing downpipe and can be difficult to install without raising the cab. If you would rather not perform any welding or do not have access to lift your cab then we recommend our pre-welded kit. Our pre-welded kit comes with a a downpipe and new uppipe that have all welding done. Our pre-welded kit comes with an uppipe that has a H/D bellow installed that is much stronger and more reliable than the OEM bellow. As an option you can also get a passenger side uppipe with a H/D bellow installed. Kit requires SCT Livewire, H&S Tuner, or Spartan Phalanx Custom Tuner to work properly. This modification is for competition use only. Installing this kit on your truck will make it illegal to use in any manner in which federal or local emission laws apply (which means pretty much any form of daily driving).
