Give your Duramax some serious room to breathe with this high-flow system that ditches restrictive factory plumbing for smooth, mandrel-bent 3-inch tubing. It pairs the legendary one-piece SuperMax Y-Bridge with a heavy-duty charge pipe to deliver massive air straight to the intake plenums.

Precision TIG-welded and fitted with laser-cut flanges, this beast delivers an impressive 202% airflow boost through a 17% shorter path to keep your diesel running wild and cool.
