GM/Chevy 6.6L DPF Delete Kits for LML, L5P, LMM & LBZ

**DISCLAIMER: Full delete kits remove or disable emissions control systems (DPF, EGR, DEF, SCR). These are for off-road use only. Street use may violate federal and state emissions laws.** GM/Chevy Duramax full delete bundles give you the power, fuel economy, and reliability your truck deserves. We stock complete kits for every generation—LLY through L5P—plus the tuners to make them work. Get your delete done right.

Complete GM/Chevy Duramax Delete Kits & Tuning Solutions

Your Duramax is built to perform. Factory emissions systems hold it back. Our full delete bundles strip out the DPF (diesel particulate filter), EGR (exhaust gas recirculation), and DEF (diesel exhaust fluid) requirements so your truck runs cleaner, leaner, and stronger.

Duramax 6.6L Diesel Full Delete Kits by Generation

2004-2005 Duramax 6.6L LLY: The original heavy hitter. Our LLY delete bundle includes everything needed to eliminate restrictive emissions hardware and unlock peak torque from your first-gen Duramax.

2006-2007 Duramax 6.6L LBZ: LBZ owners see the biggest gains post-delete. Factory DPF regen cycles kill your fuel economy—we solve that with a complete delete solution.

2007.5-2010 Duramax 6.6L LMM: LMM trucks got the first EGR cooler issues. Our full delete bundle prevents coolant contamination and restores the reliability Duramax is known for.

2011-2016 Duramax 6.6L LML: The LML platform dominates used truck lots—and our LML delete bundle is our most popular kit. Pair it with EFI Live Autocal V3, H&S Mini Maxx, or Ez Lynk Auto Agent 3 tuners for complete control.

2017-2023 Duramax 6.6L L5P: Newest Gen Duramax. The L5P delete bundle handles the complex L5P emissions system and gets your truck back to factory intent—raw power, zero restrictions.

Canyon/Colorado 2.8L Duramax (2016-2022)

Mid-size diesel owners don't settle for half measures. Our Canyon/Colorado 2.8L delete bundle delivers the same quality and performance as our full-size kits, tuned specifically for the smaller displacement platform.

Duramax 3.0L LM2 Delete Bundle (2020-2022)

The newest small-displacement Duramax in Silverado/Sierra. Our LM2 delete kit handles the latest emissions architecture so you get modern power without modern restrictions.

What's the difference between an LML and L5P Duramax delete?

The LML (2011-2016) and L5P (2017-2023) run completely different emissions architectures. LML deletes focus on DPF removal and EGR tuning; L5P deletes are more complex due to added SCR (selective catalytic reduction) systems. Don't swap kits between generations—use the correct bundle for your truck's year and engine code.

Do I need a tuner with my delete kit?

Yes. A delete kit removes the hardware; a tuner recalibrates your engine's computer to run without it. Without tuning, you'll get check engine lights and poor performance. Every bundle we sell includes tuner options—EFI Live, H&S Mini Maxx, or Ez Lynk work with most Duramax generations.

Will a Duramax delete hurt my engine?

No—if done right. Factory emissions systems reduce power and fuel economy while adding heat and soot. A quality delete kit and proper tuning actually improve engine longevity by eliminating EGR cooler corrosion, DPF regen cycles, and DEF system failures. Your engine runs cleaner and cooler.

Can I use a delete kit on the street?

Not legally. Federal emissions law prohibits the removal or defeat of OEM emissions equipment on highway vehicles. Deletes are for off-road and competition use only. Street use carries fines, failed inspections, and potential legal liability.

Which year Duramax should I buy if I want to delete?

2011-2016 LML trucks are the delete sweet spot—proven platforms, affordable prices, and the most tuning options available. If you want newest tech, the 2017+ L5P handles deletion well but costs more upfront. Avoid 2007.5-2010 LMM trucks unless you already own one—they're more prone to EGR cooler failure and require more extensive work.

What's included in a full delete bundle?

A true full delete bundle includes DPF delete pipes, EGR delete kit, fuel system cleaners, and gaskets—everything you need for a complete install. Some bundles add SCR delete components for L5P trucks. Always confirm what's included before you order; individual delete parts won't complete the job.

Can I install a delete kit myself?

If you're mechanically skilled and have lift access, yes. Most LML and L5P deletes take 8-16 hours. If you're not confident, get a diesel shop to handle it—a bad install will cause leaks, rough running, and expensive diagnostics. Tuning must always be done by someone with tuner experience, not guessed at.
