DHD 300-125 OEM LENGTH D-PIPE STAINLESS PASSENGER LB7 UP PIPE KIT 2001-2004

DHD Stainless Up Pipe Kit (01–04 LB7 Duramax)

Includes gaskets + hardware
OEM Fit | Best Value | No Core Required

Description

These full-featured OEM-fit up pipes are an excellent value. They’re brand new, built to fit like factory, and deliver high flow and durability without the high price of an OEM replacement.

DHD takes stock replacement to the next level. This passenger-side up pipe flows up to 53% more than stock, while remaining a direct bolt-on to factory manifolds.

Unlike the factory up pipe, this kit is built from 11-gauge 304 stainless steel and includes a heavy duty internally-sleeved stainless bellow designed to handle extreme heat and pressure. It’s stronger than most competing options, weighing nearly a pound more and featuring TIG welded flanges inside and out for long-term reliability.
