How to Make L5P Louder without Deleting?

Wondering how to make L5P louder without deleting the DPF system so you can avoid a costly fine and retains the engine’s longevity? You are on the right track. You can make the L5P louder by installing a cold air intake, upgrading its exhaust system, replacing the turbocharger, or installing a resonator delete pipe.

These modifications will significantly increase your L5P’s sound without effective its horsepower, fuel economy, and overall value.

How to Make L5P Louder without Deleting

Deleting the DPF of the L5P engine isn’t the only way to make its sound more aggressive and louder. Below are some preferable ways to increase your L5P engine’s sound without hurting the engine or your pocket:

1. Install Cold Air Intake

Installing a cold air intake can increase the L5P sound notably. It helps the engine to get cooler air so it can burn more fuel while remaining cool for a long time. Hence the engine will deliver more power, better performance, and louder noise.

Install Cold Air Intake

Even, you won’t have to replace the exhaust to install a cold air intake. It’ll cost between $100 and $500 to install a new cold air intake to get a louder and more aggressive sound.

2. Upgrade the Exhaust System

Upgrading the stock exhaust improves the engine’s power and sound. Adding a top-notch muffler exhaust system to the engine also ensures better gas flow through the exhaust. Hence the engine will deliver improved performance and more aggressive sound. Installing an exhaust system will also boost the engine’s longevity instead of impacting the factory emissions.

Upgrade the Exhaust System

Though standard exhaust systems cost around $75 to $100, an advance one can cost over $300. However, you must check the state’s law before changing the factory exhaust as many states only allow a certain level of engine noise.

3. Replace the Turbocharger

Replacing a turbocharger can’t directly make the truck sound louder. It increases the engine’s overall torque values and horsepower and makes the exhaust louder.

Replace the Turbocharger

However, replacing a turbocharger is a time-consuming and tiresome process and needs to replace plenty of other parts. So, it can cost between $450 and $2800 to change the turbocharger.

4. Install a Resonator Delete Pipe

Installing a resonator delete pipe can also be a possible way to make the L5P louder, particularly without deleting the DPF. It is also simpler to install a resonator delete pipe and only requires some hand tools. However, you may experience louder cabin noise after changing the resonator.

Effect of Deleting L5P DPF

Though deleting the DPF can make the L5P louder, it’ll bring lots of consequences.  Let’s understand some effects of deleting the DPF from your L5P engine:

Don’t Restrict Horsepower

Many people believe that installing a bigger intake and exhaust for the 2017 to 2020 L5P can make it more powerful. Though many forums convince them to believe so, it isn’t factual.

Don’t Restrict Horsepower

It can manipulate other critical commands in the engine like fuel, timing, and boost. so it won’t increase the horsepower notably.

Won’t Deliver Better Fuel Economy

Deleting the DPF can improve only a little fuel economy that can be noticeable hardly. Instead, you should remove the EGR to improve the fuel economy significantly. This’ll ensure a more free flow of exhaust gases to let the engine breathe easily.

Reduce the Trucks Durability

GM and other competitors upgrade their factory emissions components. The components that they first used on their trucks like EGR, DPF, and UREA were very poor and required frequent repair.

Reduce the Trucks Durability

But their upgraded components last forever and don’t harm the truck’s operation. Emission is a vital part of a vehicle. You should maintain it and allow it to complete the full cycle instead of modifying it for making the engine louder.

Legal Implications

Deleting the emissions is expensive as you’ll be charged a fine due to missing the emissions equipment. It’ll make your car illegal and void the warranty. So if you want to avoid a hefty fine and keep the vehicle in good condition, don’t remove the DPF.

Reduce the Trucks value

If you delete the DPF system, it’ll limit the opportunity to sell the truck or trade it to a dealer. Even you may end up looking for a new emission system to make the truck applicable for selling.

Though you can sell your truck without emission to a third party, you won’t get the desired money. So if you don’t want to struggle to sell the vehicle, keep the emissions equipment and DPF with your truck.


Why does a person tend to delete an L5P?

Many people believe that deleting the DPF system of an L5P engine can prevent tiresome maintenance and improve its performance. they think it can reduce the expensive repairs and ensure more power production.

What is the penalty for deleting DPF?

Deleting DPF is highly illegal. If you remove any emissions components from the diesel engine and install non-SMOG-complaint equipment, you can fine up to $5000.

Does increasing the bore of the exhaust pipe make its sound deeper?

Yes, it should work. With wider pipes, sound faces fewer obstacles and increases. If you add some size to the exhaust pipe, it can help the vehicle to produce a roaring sound. However, you shouldn’t bore the exhaust pipe too much.

Final Words

Hope you understand how to make L5P louder without deleting. Though adding a cold air intake or exhaust system may cost a little money this will provide you with much louder sound while improving the car’s overall performance.

Deleting the DPF system on the other hand isn’t a worthwhile decision in any case. It’ll make your car illegal for the road, cost you a higher fine and reduce the car’s durability and longevity. If you prefer a louder sound out of the L5p engine, do it sensibly.
