Description

The Wehrli 3in Stainless Down Pipe is a high-flow exhaust component designed for 2004.5-2010 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks with the 6.6L Duramax Diesel V8 engine. This downpipe replaces the restrictive factory turbo down pipe and exhaust front pipe. It features a 3-inch diameter, stainless steel construction, and includes heat wrap.

Installation does not require tuning and it is made in the USA. This part replaces GM Part Number 98050150. However, it cannot be shipped to California and is subject to California's Prop 65 warning regarding cancer and reproductive harm.
