Give your Duramax some serious room to breathe by kicking that restrictive factory plumbing to the curb. This killer combo replaces the sluggish post-intercooler plumbing, two-piece Y-bridge, and factory driver-side charge tube with full 3-inch mandrel-bent, TIG-welded tubing designed to feed massive amounts of fresh boost directly to your engine.

Crafted with precision CNC-machined flanges, heavy-duty 5-ply silicone couplers, and stainless T-bolt clamps, it provides bulletproof reliability and shorter, smoother flow paths. It is an all-in-one upgrade that turns up the fun factor under the hood while delivering maxed-out airflow for your off-road adventures.
