Description

The SPELAB exhaust up-pipe is a performance upgrade for 2017-2023 L5P 6.6L Duramax Diesel GMC Sierra and Chevrolet Silverado 2500/3500 HD trucks. This component serves as the crucial link between the exhaust manifolds and the turbocharger, efficiently channeling high-temperature exhaust gases. Reinforced flex sections are incorporated to significantly reduce the risk of cracking, a common failure point in stock components. SPELAB provides this up-pipe in several configurations to meet specific needs, including options that are EGR-compatible or modified, allowing for emissions compliance when choosing the former. While straightforward in concept, the location within the engine bay may necessitate specialized tools and mechanical experience for proper fitment. While its primary function is to enhance reliability and exhaust flow, it can contribute to improved turbo efficiency and throttle response, potentially supporting mild horsepower gains when combined with other performance modifications.
