The Truth About DPF Delete Shops: What You Need to Know

So you’ve been driving your diesel truck for a while now and have started noticing some loss of power and lower fuel economy. Chances are your diesel particulate filter or DPF is clogged up with soot and needs to be cleaned or replaced. Before you head to the dealer and shell out big bucks for a new DPF, you may want to consider visiting a DPF delete shop to have your filter removed altogether. A DPF delete 6.7 cummins can restore your truck’s performance and save you money in the long run. However, there are some important things you need to know before going down this route.

What Does a DPF and What Does a DPF Delete Mean?

A DPF is a diesel particulate filter. It captures and stores exhaust soot to reduce emissions from diesel engines. DPF delete means removing or disabling your vehicle’s DPF to improve performance, but it’s illegal and harms the environment.

DPFs filter out soot and other particles from diesel exhaust before they leave the exhaust system. They help diesels meet emissions standards and reduce pollution. However, DPFs can reduce engine power and fuel economy over time as they fill up with soot. Some owners delete their DPF to restore lost performance, but this is illegal and damages the environment.

Instead of deleting your DPF, the best approach is to keep it clean and functioning properly. Here are some tips:

  1. Drive at highway speeds when possible. Driving fast helps burn off trapped soot in the DPF through a process called passive regeneration.
  2. Avoid excessive idling. Idling for long periods prevents the DPF from self-cleaning and can clog it up faster.
  3. Use a diesel additive. Additives containing detergents can help break down soot buildup and keep your DPF clean.
  4. Have the DPF serviced if needed. If your DPF is very clogged, it may need professional cleaning or replacement to restore engine performance and avoid the need for a delete.
  5. Consider an EGR delete instead. Deleting your EGR valve can also improve performance without removing the DPF. But EGR deletes are still illegal for on-road use.

Keeping your DPF clean and functioning is the responsible and legal option. DPF delete shops may promise more power or better fuel economy, but deleting your DPF harms the environment and violates emissions laws. It’s just not worth the risk.

The Risks and Consequences of Deleting Your PDF

Deleting your diesel particulate filter (DPF) may seem tempting, but it comes with major risks and consequences you need to consider first.

You could face hefty fines if caught without a DPF. Most areas have emissions laws prohibiting tampering with or removing anti-pollution devices. Get caught and you’ll have to pay to have a new DPF installed, plus penalties.

Reduced Engine Life

That DPF filters out soot and other particles that can damage your engine and turbocharger over time. Without it, your engine and turbo life expectancy goes way down. We’re talking sludge buildup, oil contamination, and part corrosion that leads to premature failure.

Terrible Fuel Economy

Expect your miles per gallon to drop like a rock. That DPF actually helps your engine run more efficiently. Without it, your engine has to work harder, burning more diesel to do the same job.

Environmental Impact

DPFs reduce hazardous diesel emissions like particulate matter, hydrocarbons, and carbon monoxide. Deleting yours means pumping tons more pollution into the air we all breathe. Not cool.

Resale Value Plummets

Good luck selling a used diesel vehicle with a deleted DPF. Most buyers know the risks and will avoid it like the plague. You’ll have to sell at a major loss if you can even find a buyer.

At the end of the day, DPF deleting just isn’t worth the money you might save upfront. There are better options if you want to improve performance, like a DPF back exhaust or ECU remap. Do the right thing—leave your DPF intact. Our lungs and wallets will thank you for it!

Warning Signs You May Be Dealing With an Illegitimate DPF Delete Shop

When searching for a DPF delete shop, be on the lookout for warning signs that the shop may not be operating legally or ethically. Some red flags to watch out for:

Pushy sales tactics

Suppose a shop is pressuring you into a DPF delete or making big promises about huge increases in horsepower or fuel economy. In that case, that’s a sign they may be more interested in making a sale than doing quality work. Reputable shops will educate you on the pros and cons of a DPF delete so you can make an informed choice.

No mention of emissions laws

In many areas, tampering with or removing your DPF is illegal. Legitimate shops will be upfront about emissions regulations in your region and whether a DPF delete would violate them. If a shop doesn’t bring this up, they may not care about compliance or your safety.

Low prices

While a good deal is always nice, be wary of shops offering DPF deletes at a fraction of the typical cost. They may be using subpar parts or inexperienced technicians to cut corners. It’s best to get multiple estimates to determine a fair price range.

No warranty

Reputable DPF delete shops will offer some kind of warranty on parts and labor, typically 6 months to 2 years. If a shop offers no guarantee of their workmanship, it’s a sign they don’t stand behind what they do.

Cash only

While some smaller shops may prefer cash, refusing all other payment methods is suspicious. Legitimate businesses have no reason not to accept credit cards, checks or other options. Cash-only policies can indicate the shop is trying to avoid reporting income or keep no records of transactions.

When choosing a DPF delete shop, trust your instincts. If something feels off, keep looking. Your vehicle’s performance and safety depend on finding a shop committed to quality work and customer satisfaction. It’s worth taking the time to find a shop you can build a long-term relationship with.

How to Find a Reputable Shop for DPF Modifications

Finding a reputable shop to delete your diesel particulate filter (DPF) and modify your exhaust system can be challenging. Here are some tips to help you locate a shop you can trust:

Check Online Reviews

Search for DPF delete shops in your area and read through the reviews on sites like Yelp, Google, and Facebook. Look for shops with mostly positive reviews mentioning good experiences, fair pricing, quality work, and customer service. Avoid any shops with reviews complaining of shoddy workmanship, excessive fees, or rude staff.

Ask About Experience

Call a few of the top-rated shops and ask how long they’ve been doing DPF deletions and diesel performance mods. An experienced shop, especially one that specializes in diesel trucks, will be well-versed in all aspects of DPF deletes and exhaust upgrades. They’ll also likely have a proven track record of satisfied customers.

Inquire About Parts and Tuning

A reputable DPF delete shop will use high-quality, name brand parts specifically designed for your truck make and model. Cheaper, generic parts can reduce performance and durability. They should also offer ECU reprogramming to maximize engine power and fuel efficiency after the DPF removal. Reputable tuners and programmers like Banks Power and Bully Dog are a good sign.

Check for Proper Certification

Many areas require special certification to legally perform DPF deletes and other emissions system modifications. Ask if the shop and its technicians carry the proper certifications for your state or county. Reputable shops will follow all laws regarding emissions compliance in your area.

Request References

Don’t hesitate to ask the shop for references from previous customers, especially those with trucks similar to yours. Speaking with someone who’s had firsthand experience with the shop’s work can give you confidence in their skills and service.

By doing your homework, you can find an experienced DPF delete shop that will perform quality work you can trust. Your truck’s performance and reliability depend on it!

Maintaining Your Diesel After DPF Removal: Best Practices

Now that your diesel’s DPF has been removed, it’s important to properly maintain your vehicle to keep it running well. Following these best practices will help your diesel thrive for years to come:

Use High-Quality Diesel Fuel

Only put ultra-low sulfur diesel (ULSD) fuel in your tank. ULSD has a sulfur content of 15 ppm or less and is required for all diesel vehicles. Using regular diesel can damage your engine and void any warranties.

Change Oil Regularly

With the DPF gone, soot and other contaminants can build up in your engine oil more quickly. Stick to the recommended oil change interval in your owner’s manual, usually around every 3,000 to 7,500 miles depending on your vehicle and driving conditions. Using high-quality motor oil designed for diesel trucks is also a must.

Clean Intake and Exhaust

Over time, soot and carbon can accumulate in your intake manifold, intake valves, exhaust manifold, and turbocharger. Use a diesel intake and exhaust treatment, like a solvent-based cleaner, to prevent buildup. Follow the directions to run it through your engine every few oil changes or if you notice reduced power or strange noises.

Monitor Engine Performance

Pay attention to your engine sounds and performance. Listen for strange knocking, squealing or rattling noises that could indicate engine damage or wear. Notice drops in power, acceleration or fuel economy, which can also signal issues. Check your dashboard for any warning lights and scan for diagnostic trouble codes. Addressing problems early on can help prevent costly repairs down the road.

Consider an Extended Warranty

With the DPF removed, your factory warranty is voided. Purchasing an extended warranty or vehicle service contract can give you peace of mind in case of any major engine or emissions system failures. Reputable companies offer plans tailored to modified diesel trucks. Do your research to find one that suits your needs and budget.

Following these best practices for maintenance and care will help keep your deleted diesel truck running strong for the long haul. Stay on top of any issues and your truck will reward you with many more miles of enjoyable driving.


You now know the truth about DPF delete shops. It may seem tempting to save money upfront by removing your, but it’s just not worth the long-term costs and risks. Your health, the environment, and your vehicle’s performance are very important. Instead, find a reputable shop that properly diagnoses and fixes your, or replace it if needed. They can get your diesel running right while keeping it fully emissions-compliant. Don’t fall for the empty promises of cheaper, illegal shortcuts. Make the choice that lets you breathe easy – in more ways than one! Stay safe out there and keep on truckin’ the legal and responsible way. To get a discount please visit this link:
