Buying Guide for best exhaust for duramax lly

Types of Exhausts for Duramax LLY

When it comes to the exhaust system of your Duramax LLY, there are a few types of exhausts to choose from. The most common types are:

Single-exit exhaust: This is the most basic option and is often the cheapest. It uses one pipe to exit the gases from the engine, resulting in a loud, throaty sound.

Dual-exit exhaust: This type of system utilizes two pipes to exit the gases from the engine. It produces a slightly quieter sound than a single-exit system, but still provides an aggressive tone.

Cat-back exhaust: This type of system is more expensive than a single or dual-exit system and requires more labor to install. A cat-back exhaust utilizes two pipes that come from the catalytic converter back and exit at the rear bumper. It produces a deeper, more refined sound than either single or dual-exit systems.

Turbo-back exhaust: This is the most expensive option but also provides the greatest performance gains. A turbo-back system replaces all piping from the turbocharger back (including catalytic converter) and exits at the rear bumper with either one or two pipes depending on your preference. It produces an even deeper and louder sound than a cat-back system, but also gives greater performance gains due to improved air flow.

Considerations when Choosing an Exhaust System

There are several factors you should consider when selecting an exhaust system for your Duramax LLY:

Sound: The type of sound you want is largely based on personal preference, but its important to consider how loud you want your truck to be before making a purchase.

Performance Gains: If youre looking for performance gains, then its best to opt for either a cat-back or turbo-back system as these provide greater air flow and result in better performance gains over single or dual-exit systems.

Cost: The cost of an exhaust system can vary greatly depending on which type you choose and how much labor is required for installation. Make sure you have an accurate estimate of what it will cost before making a purchase so you dont end up spending more than you intended.

Best Exhaust Systems for Duramax LLY

When it comes to choosing an exhaust system for your Duramax LLY, there are many great options available on the market today that can provide great performance gains as well as improved sound quality. Here are some of our top picks that we recommend checking out if youre in need of a new exhaust system for your Duramax LLY:

MagnaFlow Single Exit Exhaust System This single exit system provides great sound at an affordable price point and comes with all necessary hardware for installation.

Flowmaster Dual Exit Exhaust System For those looking for slightly more refined sound without breaking their budget, this dual exit Flowmaster system can provide just that while still offering great performance gains over stock systems.

MBRP Cat Back Exhaust System If youre looking for maximum performance gains without sacrificing too much on sound quality then this MBRP cat back system is worth considering as it provides both power increases as well as improved sound output compared to stock systems.

Banks Power Turbo Back Exhaust System For those who want maximum power increases with improved sound output then this turbo back Banks Power system should be at the top of your list as it offers both these benefits with minimal compromise in terms of cost or installation time required

The best exhaust for a Duramax LLY is one that is designed to optimize exhaust flow and provide the most power and torque possible. This could be a true dual exhaust system, a single side exit exhaust system, or something in between. Whatever the choice, it should be made with performance and longevity in mind. A well-designed exhaust system can help your truck reach its full potential, while also providing a great sound.
