The 031-HSP or HSP 2 Inch Replacement Up-Pipes for the 2001-2004 Chevrolet and GMC Duramax offer a superior alternative to the factory components. Not only do they enhance performance, but they also mitigate common failure points.

 

The factory Duramax Uppipes are susceptible to failure, and an up pipe failure can result in a loss of power and potential strandedness. Therefore, proactive replacement prior to failure is crucial and can significantly impact the vehicle’s reliability.

 

**Understanding Up-Pipe Function and Failure Points**

 

Before delving into up-pipe issues, it is essential to comprehend their role. The up-pipe channels the turbo exhaust gases, which subsequently spin the turbocharger and generate boost pressure. Unfortunately, the factory up-pipes on the Duramax trucks frequently fail, and these failures often occur at inconvenient times. The primary and most common failure point of the factory up-pipe is the bellows. These components crack, leading to leaks that escalate rapidly. Additionally, warped flanges caused by faulty gaskets that cannot be repaired due to the high temperatures persist and continue to leak.

 

**The Advantages of the HSP 2 Inch Replacement Up-Pipe**

 

In contrast, the HSP 2 Inch Replacement Up-Pipe offers distinct advantages. It addresses the aforementioned issues by providing a reliable and durable solution. The up-pipe’s robust construction ensures minimal wear and tear, reducing the likelihood of failure. Additionally, its superior design mitigates the potential for leaks and warped flanges, enhancing the vehicle’s overall performance and longevity.

 

The primary distinction between the factory up-pipe and the HSP 2-inch Replacement Up-Pipe lies in its flow characteristics. The HSP 2-inch Replacement Up-Pipe offers a significantly enhanced flow rate, resulting in increased power, torque, reduced EGTs, and improved spool-up.

 

In addition to its performance enhancements, the HSP 2-inch Replacement Up-Pipe incorporates reliability improvements. The up-pipes are constructed from heavy-wall 304 stainless steel tubing, reinforced with heavy-duty sleeved bellows. This combination ensures both exceptional performance and reliability, far surpassing the capabilities of factory components.

Defective cracked
Size: Large (Pack of 3), Color: Orange, Green & Yellow, Pattern Name: Dog
The stuff inside was cracked. It took my dog a few minutes to get it out. I bought these from other stores in person and didn't have any problem. It must be from shipping and handling.

My dogs love their dental chews! This product is durable and the perfect size for each of my dogs. I've purchased two of them (medium and large). One of my dogs is an aggressive chewer and this product is holding up. Hartz makes great pet products. I'm very happy with the product.

My Winnie is an aggressive chewer and she loves these bones. They're indestructible and they must be delicious because she works on them every day. I was a bit concerned when they were out of stock for a few months. Please don't discontinue them!
