The 500-HSP or best known as the HSP Hot Side Tube for the 2011-2016 LML Duramax equipped Chevrolet and GMC trucks. The hot side pipe is something that is a common failure and necessary replacement on the Duramax trucks.

Why would you need the HSP Hot Side Tube for the LML Duramax Trucks?

The factory Hotside pipe is part that fails often on the Duramax trucks. This part is not only an issue when it fails because it is not always a quick change but also because when this fails it creates a boost leak. With a boost leak, you will be down on power and you will quickly have issues driving or towing. There is nothing you can do about the factory-style hotside tube other than replacing it with a different style.

What does the HSP Hot Side Tube do differently?

To start the HSP Hot Side Tube increases performance dramatically. With an increase of up to 40% over the factory style. The HSP Hot Side Tube makes big changes to make these increases. We start with a bump in size to 3” diameter and make sweeping bends. We use mandrel-style bends to ensure not only a proper fitment but also that the bends are as least restrictive as possible to give us less turbulence and the most efficient flow. Our design also allows for a straight connection to the intercooler, eliminating any issues with the silicone boot which is the common point for boost leaks.

What comes with the HSP Hot Side Tube?

  • (1) 3” Mandrel-bent hot side tube
  • (1) 3x4 Straight boot

What Does the HSP Hot Side Tube fit?
