The 031-HSP or HSP 2 Inch Replacement Up-Pipes for the 2001-2004 Chevrolet and GMC Duramax are great replacements to the factory parts that improve performance and lessen common failure points.

The factory Duramax Uppipes are prone to failure, and failure on an up pipe can leave you stranded, down on power, and more. This is why replacing them before failure is so important and can make or break a moment real fast

Why Would you need an HSP 2 Inch Replacement Up-pipe?
Before we get into up-pipe issues, let's talk about what an up-pipe does; the up-pipe feeds the turbo exhaust gases that then spin the turbo and create boost. The factory up-pipes on the Duramax trucks fail often; more often than not, it's when it's least convenient. The factory up-pipe's major and most common failure point is the bellows. They crack, and that causes leaks, and then it spirals from there. Other problems are warped flanges from bad gaskets that can not be repaired due to the heat and will continue to leak.

What does the HSP 2 Inch Replacement Up-Pipe Do Differently?
The biggest difference between the factory up-pipe and the HSP 2-inch Replacement is the flow. The HSP 2 Inch Replacement Up-Pipe is a different world regarding how much it flows. With better flow, we all know, comes more power, more torque,, and reduced EGT, all while increasing spool up. Now that covers the performance increase side of things, but we also have reliability fixes. Our Up-Pipes are made of heavy wall 304 stainless steel tubing. We then put heavy-duty sleeved bellows into our stainless steel tubing to create an up-pipe capable of performance and Reliability far beyond the factory parts.
