PPE has addressed this restrictive component of your truck's exhaust and created their 3" Stainless Steel Downpipe for improved power and performance over stock. 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, allowing your truck to perform and function properly without the loss of energy caused by the restrictive tailpipe, giving your truck more power and torque for heavy-duty applications. This will also help improve your truck fuel economy overtime to help you save a bit of cash in the long run. This massive downpipe attaches right after the turbo inlet outlet which is where the gases are expanding fastest as they cool off on their way out.
