What is the L5P Duramax?

The L5P Duramax is a 6.6L turbo-diesel engine. It’s used in 2017–2023 Chevy Silverado 2500/3500 and GMC Sierra 2500/3500 trucks. Known for strong towing and reliability, this engine still has one big frustration: emissions systems. Components like the DPF, EGR, and DEF can limit performance and add maintenance headaches.

What is an L5P Delete Kit?

An L5P delete kit removes or modifies emissions parts. The goal is to unlock horsepower, improve fuel economy, and reduce repair costs. Here’s what’s inside a typical kit:

If you are a car enthusiast considering upgrading your vehicle's performance, you've likely heard about long tube headers. These high-performance components can significantly enhance engine output and sound. However, the legality of long tube headers is always the question and then "to go(buy) or not to go(buy)" is also the question. Almost everyday we would get questions from customers like-
Are any long tube headers 50 state smog legal?
Can I pass emissions with long tube headers?
Are long tube headers legal in Arizona?
Are long tube headers legal in California?
Are long tube headers legal in North Carolina?
Are long tube headers legal in Texas?
Will long tube headers pass emissions?
....

The fact is the legality for installing long tube headers varies from state to state. Understanding these laws is crucial to avoid fines or complications. In this article, we will explore the legality of long tube headers across

What Are LS Swap Headers?

LS swap headers are specially designed exhaust headers used when swapping an LS engine (a popular family of GM V8 engines) into a vehicle that originally came with a different engine. They replace the stock exhaust manifolds and are engineered to optimize exhaust flow, reduce backpressure, and maximize the performance of your LS engine. These headers are necessary because the LS engine has a unique exhaust port configuration and may not fit properly with the stock exhaust system or headers of the recipient vehicle.

Key Features of LS Swap Headers:

• Improved Performance: LS swap headers are often designed to optimize exhaust flow, which can enhance engine performance and horsepower.

• Custom Fitment: Designed to fit seamlessly in vehicles with LS engine swaps, ensuring proper clearance and alignment.

The Chevrolet C/K is a series of trucks that was manufactured by General Motors from the 1960 to 2002 model years. Used for both the model branding and the internal model code, "C" denoted two-wheel drive, while "K" denoted four-wheel drive. Four generations of the C/K series were produced, including the GM monikered second-generation "Action Line" and third-generation "Rounded Line" vehicles (colloquially aka Square-Body trucks). Marketed by both the Chevrolet and GMC divisions, the C/K series encompassed a wide range of vehicles. While most commonly associated with pickup trucks, the model line also included chassis-cab trucks and medium-duty trucks and served as the basis for GM full-size SUVs.
