Wehrli 2004.5-10 Duramax LLY/LMM D/S 3in. Intercooler Pipe - Bronze Chrome

If you're looking to get more airflow to your Duramax engine, especially if you've been running higher boost levels, this driver side intercooler pipe from Wehrli Custom Fabrication is a solid upgrade. It's designed to replace the factory 2 1/2 inch pipe with a full 3 inch diameter, which helps reduce restrictions and allows your turbo to breathe easier. This is particularly helpful because the stock pipe has a bead roll design at the turbo connection that can actually blow off under increased boost, something this Wehrli pipe avoids.

This pipe is built as a single piece, which means fewer potential leak points compared to multi-piece designs. It comes with high-pressure rated silicone boots and T-bolt clamps, ensuring a secure and leak-free connection that's less likely to come loose, even with more aggressive tuning. The bronze chrome finish isn't just for looks; it's a durable two-stage powder coating that holds up well under the hood. This pipe fits a wide range of Duramax trucks, including models like the 2007 Chevrolet Silverado 2500 HD and the 2008 GMC Sierra 3500 HD.
