Description

The HSP Diesel 2" Replacement Up-Pipes are designed to replace the factory parts for 2001-2004 GM Duramax trucks. These up-pipes are made from heavy wall 304 stainless steel tubing and feature heavy-duty sleeved bellows.

They are intended to improve performance by offering better flow, which can lead to more power, increased torque, reduced Exhaust Gas Temperatures (EGTs), and quicker turbo spool-up. The robust construction aims to enhance reliability beyond the factory components.
