The Duramax LML engine is renowned for its power and durability, making it a popular choice for those looking to build high-performance diesel trucks. Achieving over 700 horsepower requires not only a robust engine but also the right upgrades to ensure optimal performance. Among the most critical upgrades are the exhaust and intake systems. This article will explore the best options available for enhancing your Duramax LML build.
Why Upgrade Your Exhaust and Intake?
Upgrading the exhaust and intake systems of your Duramax LML engine can significantly impact its performance. Here are a few reasons why these upgrades are essential:
- Increased airflow for better combustion
- Improved turbocharger efficiency
- Enhanced throttle response
- Reduction in turbo lag
- Better fuel economy
Best Exhaust Upgrades for 700+ HP Duramax LML
Choosing the right exhaust system is crucial for maximizing the performance of your Duramax LML. Below are some of the top exhaust upgrades that can help you achieve your horsepower goals:
1. 5-Inch Turbo Back Exhaust System
A 5-inch turbo back exhaust system is a popular choice among Duramax enthusiasts. This upgrade allows for increased exhaust flow, reducing back pressure and improving turbo efficiency. Brands like MBRP and Flo-Pro offer high-quality options that are designed to withstand high temperatures and pressures.
2. High-Performance Muffler
Replacing the stock muffler with a high-performance option can make a significant difference in sound and performance. Look for mufflers designed to reduce restriction while maintaining a deep, aggressive tone. Options from brands like AFE and MagnaFlow are popular among Duramax owners.
3. Performance Exhaust Tips
While exhaust tips may seem like a cosmetic upgrade, they can also enhance exhaust flow and add a stylish touch to your truck. Consider options with larger diameters and unique designs for both aesthetics and performance benefits.
Best Intake Upgrades for 700+ HP Duramax LML
Just as important as the exhaust system, the intake system plays a vital role in engine performance. Here are some of the best intake upgrades for your Duramax LML:
1. Cold Air Intake System
A cold air intake system is one of the most effective upgrades for increasing horsepower. By allowing cooler, denser air into the engine, these systems improve combustion efficiency. Brands like S&B and K&N offer excellent options that are easy to install and provide noticeable performance gains.
2. High-Flow Air Filter
Upgrading to a high-flow air filter can enhance airflow while providing better filtration. This upgrade is often compatible with stock intake systems and can help maintain engine cleanliness. Look for filters from reputable brands like AFE or S&B for optimal performance.
3. Intake Elbow Upgrade
Replacing the factory intake elbow with a high-performance version can improve airflow and turbo response. Aftermarket elbows are typically designed to reduce restriction and enhance the overall performance of the intake system.
Combining Exhaust and Intake Upgrades
For the best results, it’s essential to combine both exhaust and intake upgrades. A well-matched system will ensure that your Duramax LML can breathe better and perform at its peak. Here are a few tips for optimizing your upgrades:
- Choose components from the same manufacturer for compatibility
- Consider tuning your engine to maximize performance gains
- Ensure all parts are installed correctly to prevent leaks
Conclusion
Upgrading the exhaust and intake systems of your Duramax LML is a crucial step towards achieving over 700 horsepower. By selecting high-quality components and ensuring proper installation, you can unlock the full potential of your engine. Whether you’re looking for improved performance on the road or at the track, these upgrades will provide the boost you need for your Duramax build.
