Large Diameter Downpipe for Ultimate Free-Flowing Exhaust

When searching for ways to improve the power and efficiency of a GM Duramax truck, many overlook the restrictive factory turbo direct pipe. Fortunately, PPE tackles this issue with their 3" Stainless Steel Downpipe, designed to significantly boost power and performance compared to the stock unit. This premium replacement downpipe was engineered to shorten turbo lag by maximizing the amount of flow coming from the exhaust. Improved flow means less back-pressure, giving your truck more power and torque for heavy-duty applications. Additionally, this will help improve your truck fuel economy to help you save a bit of cash in the long run. The massive downpipe connects directly after the turbo inlet outlet, where exhaust gases expand rapidly as they exit, ensuring optimal performance.
