HSP 2 Inch Replacement Up-Pipes for 2001-2004 Chevrolet / GMC Duramax

The 031-HSP or HSP 2 Inch Replacement Up-Pipes are high-performance replacements for the factory up-pipes on 2001-2004 Duramax trucks. They offer improved reliability, performance, and durability—addressing some of the most common OEM failure points.

Why Would You Need HSP 2 Inch Replacement Up-Pipes?

The up-pipes are essential—they feed exhaust gases to your turbo, generating boost. The factory units are prone to failure, especially at the bellows. These failures can lead to power loss, excessive heat, and inconvenient breakdowns. Replacing them before failure is key to protecting your trucks performance.

What Makes HSP Up-Pipes Different?

HSPs 2-inch up-pipes significantly improve exhaust flow, which translates to more power, lower EGTs, faster spool-up, and greater torque. Built from heavy-wall 304 stainless steel with reinforced sleeved bellows, these up-pipes are engineered to withstand high heat and pressure far better than OEM units.
