Removing the EGR system with a
duramax egr delete kit from Flashark Racing could potentially void warranties or affect insurance coverage for Duramax vehicles, as it involves modifying factory-installed emissions components. However, the impact on warranties and insurance coverage may vary depending on local regulations and individual policies. While EGR removal is one method to enhance performance, there are aftermarket products and modifications available that can improve Duramax engine performance without removing the EGR system entirely, such as tuning upgrades, intake and exhaust modifications, and performance chips. Regarding longevity and reliability, improper EGR removal or inadequate tuning could potentially impact the long-term reliability of a Duramax engine, emphasizing the importance of proper installation and tuning.
