The HSP 2 Inch Stock Replacement L5P Up Pipe Bundle is designed for 2017-2025 Chevrolet and GMC Duramax-equipped trucks looking to improve reliability, exhaust flow, and overall turbocharger performance. The factory up-pipes are a known weak point on the L5P platform, especially under increased boost and towing conditions.

HSP Diesel engineered this replacement bundle to eliminate those common failure points while increasing durability and performance.

The factory up-pipes are responsible for routing exhaust gases from the exhaust manifolds to the turbocharger. Over time, the factory bellows can crack or fail due to repeated heat cycles and increased exhaust pressure.

These failures can lead to exhaust leaks, reduced turbo efficiency, excessive heat, loss of power, and poor drivability.

Replacing the factory up-pipes before failure helps protect your truck from costly downtime while improving overall exhaust flow and turbo response.

HSP Diesel's replacement up-pipes are constructed from heavy-wall 304 stainless steel tubing for superior strength and long-term durability. The reinforced sleeved bellows are designed to handle higher temperatures and boost pressures far better than the factory components.

The optimized 2-inch design improves exhaust flow efficiency, helping reduce EGTs while improving turbo spool-up, throttle response, horsepower, and torque. Whether your truck is stock, tuned, towing, or heavily modified, these up-pipes are built to perform.
