About this product
Description
Wehrli's Stage 1 airflow bundle for the 2017-2019 L5P Duramax: a 3" hot side pipe to replace the restrictive two-piece 2.5" factory pipe with its resonator, and a 3.5" cold side pipe to replace the leak-prone two-piece plastic and rubber factory pipe. It bolts on with no tuning, so it works on a stock truck as well as a built one.
A CNC-machined flange with double O-rings seals the intercooler connection, and the factory clip ring at the Y-bridge is replaced by a silicone boot and stainless T-bolt clamps that hold higher boost without leaking. Retains factory connection points and sensors. Includes silicone boots, T-bolt clamps, O-rings and intercooler outlet clip. Powder coated in your choice of colour.
