Combined with heavy-duty four-ply silicone boots and stainless steel T-bolt clamps, this kit provides a durable and performance-focused upgrade that complements other engine modifications.
Sinister Diesel 6.7L Powerstroke EGR Delete Kit
Sinister Diesel is a recognized name in the performance industry, and their EGR delete kit is designed to improve engine efficiency and reliability. The Exhaust Gas Recirculation (EGR) system reintroduces soot and exhaust gases into the intake, which can cause carbon buildup and increase engine operating temperatures. This kit removes that system entirely.
By eliminating the EGR system, you can achieve cleaner intake air, lower engine temperatures, and improved throttle response. For those focused on engine longevity and performance, this kit from a reputable manufacturer provides a solid solution for a critical delete.
HSP Diesel 6.7 Powerstroke DPF Delete Pipe Kit
The Diesel Particulate Filter (DPF) is a major source of exhaust restriction, which can hinder performance and fuel economy. The HSP Diesel DPF delete pipe kit replaces this restrictive component with a straight-through pipe, significantly reducing backpressure. This reduction allows the turbo to spool more freely and the engine to expel exhaust gases more efficiently.
Lower exhaust backpressure often results in noticeable gains in horsepower and torque, along with improved fuel efficiency. This kit is a fundamental component for anyone looking to maximize the performance potential of their 6.7 Powerstroke by removing a key factory restriction.
Dirty Diesel Complete EGR & DPF Delete Kit
For a comprehensive solution, the Dirty Diesel kit addresses both major factory emissions systems in one package. This complete kit includes all the necessary components to delete both the EGR and DPF systems simultaneously. Performing both deletes together provides a synergistic effect for engine performance and reliability.
This approach results in the combined benefits of a cleaner intake, lower engine temperatures, reduced exhaust backpressure, and a solid foundation for significant power tuning. It is an ideal all-in-one solution for owners ready to fully optimize their 6.7 Powerstroke’s operation and capability.
Buying Guide: How to Choose the Best 8.7 Powerstroke Delete Kit for Performance and Reliability 2025
When I started looking into delete kits for my own 6.7 Powerstroke, I quickly realized it wasn’t just about buying a random set of parts. The goal is to improve performance and, more importantly, long-term reliability. The market is flooded with options, so knowing what separates a good kit from a great one is crucial. Let’s talk about what I believe you should prioritize.
First, you need to decide between a full delete kit and a partial one. A full kit is what most of us are after. It typically includes everything to remove the Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR) system, and the Exhaust Gas Recirculation (EGR) system. This comprehensive approach addresses the two biggest failure points on these engines. A partial kit might only tackle one system, which can be a temporary fix but often leaves the other major restriction and failure point in place. For a true transformation in how the truck runs and lasts, a full delete is the way to go.
The quality of the components is non-negotiable. Look for kits that use T304 or T409 stainless steel for the exhaust piping. This material resists corrosion and can handle the high temperatures, ensuring your new system lasts for the long haul. I also pay close attention to the included tuner. This is the brain of the operation. A reputable, well-supported tuner from a known company is essential. It’s not just about adding power; a good custom tune will properly manage engine parameters after the emissions equipment is gone, which is vital for engine health. A cheap, generic tune can cause more harm than good.
Finally, consider the completeness of the kit. The best 8.7 Powerstroke delete kit for performance and reliability 2025 will have all the necessary hardware, gaskets, and connectors. There’s nothing more frustrating than being halfway through an installation and realizing you’re missing a crucial clamp or a block-off plate. I always check product listings and reviews to see if others mention the kit being complete and if the instructions are clear. A kit from a vendor with strong customer support can be a lifesaver if you hit a snag during the install.
Frequently Asked Questions
Is deleting my 6.7 Powerstroke legal?
This is the biggest question, and the straightforward answer is no, it is not legal for use on public roads in the United States and several other countries. The Clean Air Act prohibits tampering with federally mandated emissions control systems. A delete is strictly for off-road or competition use. Operating a deleted truck on public highways can result in significant fines for you and the shop that performed the work.
What are the real-world reliability benefits of deleting?
The primary benefit I’ve seen and heard from countless other owners is the elimination of the EGR and DPF systems. The EGR system recirculates soot and exhaust gases back into the intake, which can lead to carbon buildup and potential engine issues. The DPF system is prone to clogging and requires expensive, active regeneration cycles. Removing these systems reduces engine operating temperatures, minimizes soot-related wear, and prevents costly DPF/SCR replacements, which dramatically improves long-term reliability.
Will I see a significant improvement in fuel mileage?
Yes, this is one of the most noticeable improvements. The engine is no longer working hard to push exhaust through a restrictive DPF, and it doesn’t have to perform fuel-intensive regeneration cycles. Most users, including myself, report an increase of 2 to 5 MPG after a proper delete and tune. The engine just runs more efficiently without the emissions equipment creating backpressure and consuming extra fuel.
Do I need a custom tune, or are pre-loaded tunes sufficient?
While many tuners come with pre-loaded “canned” tunes that are better than nothing, I always recommend a custom tune from a reputable tuner. A custom tune is tailored to your specific truck, its modifications, and your driving style. It ensures the engine is running optimally for both performance and safety, managing factors like transmission shifting and boost levels much more effectively than a generic file. It’s an investment that pays for itself in drivability and engine longevity.
Can I install a delete kit myself, or do I need a professional?
This depends entirely on your mechanical skill level and tool availability. The physical removal of the DPF and EGR components is a demanding but straightforward job for someone experienced with turning wrenches. However, the tuning process requires a specific device and software knowledge. If you’re not confident in your abilities, especially with the electronic tuning aspect, paying a professional shop that specializes in diesel performance is the safest and most reliable route to take.
What should I look for in the best 8.7 Powerstroke delete kit for performance and reliability 2025?
Focus on three things: component quality, tuner reputation, and completeness. Look for T304/T409 stainless steel exhaust components to fight corrosion. Choose a kit that includes or is paired with a tuner from a well-known, trusted company with a track record of reliable and safe tuning files. Finally, make sure the kit has all the necessary parts—downpipe, straight pipe, EGR delete plates, gaskets, and hardware—so you aren’t stuck waiting for a single missing bolt.
