Description

Since the beginning of diesel performance time, one of the most popular upgrades to anything with four wheels is that of the exhaust system. Some keep it simple and just bolt on a polished tip while others will replace the entire system for larger benefits. But what are really the benefits of upgrading the exhaust on an L5P Duramax? Well, that really depends on how far you want to go. There are numerous systems out there to achieve better power, greater fuel economy, more durability, and yes.....sound! The factory exhaust system found on the Duramax equipped GM's has continuously been progressing over the years in order to comply with various emissions regulations, which has caused the exhaust manufacturers to bend and flex to keep up with the times. We offer countless variations to upgrade your Duramax from simple components to complete upgrades from the best manufacturers in the industry to include AFE, Diamond Eye, MBRP, Magnaflow, Mel's Manufacturing, and Silverline.
