Understanding the Power Behind Each Part
Straight Exhaust: Eliminate DPF Clogs & Boost Efficiency
Our stainless‑steel delete and straight pipes remove the restrictive factory DPF—so you’ll never have to deal with clogged filters again. By dramatically improving exhaust flow and cutting backpressure, you’ll enjoy faster turbo spool, lower EGTs, and better fuel economy. Offered in budget‑friendly T409 stainless, this mandrel‑bent, bolt‑on design fits your Powerstroke straight out of the box—no extra mods needed.
EGR Delete Kit: Eliminate Soot, Improve Reliability
The full EGR Delete Kit removes the factory cooler and valve to prevent soot buildup and cooler failure. Precision CNC‑machined block‑off plates seal off old ports, while high‑temperature hoses reroute coolant seamlessly. By eliminating this emissions component, you’ll see more stable combustion temperatures, extended engine life, and fewer maintenance headaches—especially crucial for heavy‑duty towing and off‑road applications.

Downpipe: Boost Flow, Cut Heat, Maximize Power
The downpipe features polished stainless steel with a thermal coating and heat wrap to reduce under-hood temps and protect components. It improves exhaust flow by 20% over stock, enhancing power, throttle response, and reducing turbo lag. The design fully removes the DOC for max airflow. A 4-bolt flange with pre-installed studs and a sealing ring ensures a leak-free fit. Built for durability and easy, no-mod installation.
