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.
Made from 304 Stainless Steel, our kit utilizes the existing EGR exhaust port, from the driver's side uppipe, to incorporate an external wastegate to allow control of high exhaust backpressure. This kit requires elimination of the EGR coolers from the vehicle.
The base kit comes with stainless steel tubing, Precision Turbo wastegate, regulator, as well as required clamps, fittings, gaskets, and hose. The base kit requires you to weld the wastegate pipe to your existing downpipe and can be difficult to install without raising the cab.
If you do not have access to any welding equipment, we recommend adding to the base kit with the welded downpipe and uppipes. If you have mild welding skills and can do minor fabrication, but do not have access to lift your cab, you can opt for the kit with only the pre-welded downpipe.
The pre-welded kit comes with a stainless steel aFe downpipe that is 2 piece and has the wastegate piping already welded for easier installation. Additionally we can include uppipes with heavy duty bellows and a welded bung for the relocated backpressure sensor. We use aFe uppipes for OE exhaust manifolds or RCD for 6.0 manifolds.
NOTE: If you have uppipes that no longer have the EGR port in the driver's side uppipe, then this kit will not work without modification.
NOTE: This kit requires the appropriate off-road tuning to work properly. Also 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).
